1. Introduction
The Si5365/66-EVB and Si5367/68-EVB provide platforms for evaluating Silicon Laboratories' Si5365/Si5366 and
Si5367/Si5368 Any-Rate Precision Clocks. The Si5365 and Si5366 are controlled directly using configuration pins
on the devices, while the Si5367 and Si5368 are controlled by a microprocessor or MCU (microcontroller unit) via
an I2C or SPI interface. The Si5365 and Si5367 are low jitter clock multipliers with a loop bandwidth ranging from
30 kHz to 1.3 MHz. The Si5366 and Si5368 are jitter-attenuating clock multipliers, with a loop bandwidth ranging
from 60 Hz to 8.4 kHz. The Si5366 device can optionally be configured to operate as a Si5365, so a single
evaluation board is available to evaluate both devices. Likewise, the Si5368 can be configured to operate as a
Si5367, so the two devices share a single evaluation board.
The Si5365/66/67/68 Any-Rate Precision Clocks are based on Silicon Laboratories' 3rd-generation DSPLL®
technology, which provides any-rate frequency synthesis in a highly integrated PLL solution that eliminates the
need for external VCXO and loop filter components. The devices have excellent phase noise and jitter
performance. The Si5366 and Si5368 jitter attenuating clock multipliers support jitter generation of 0.3 ps RMS
(typ) across the 12 kHz–20 MHz and 50 kHz–80 MHz jitter filter bandwidths. The Si5365 and SI5367 support jitter
generation of 0.6 ps RMS (typ) across the 12 kHz–20 MHz and 50 kHz–80 MHz jitter filter bandwidths. For all
devices, the DSPLL loop bandwidth is digitally programmable, providing jitter performance optimization at the
application level. These devices are ideal for providing clock multiplication/clock division, jitter attenuation, and
clock distribution in mid-range and high performance timing applications.

2. Applications
The Si5365/66/67/68 Any-Rate Precision Clocks have a comprehensive feature set, including any-rate frequency
synthesis, multiple clock inputs, multiple clock outputs, alarm and status outputs, hitless switching between input
clocks, programmable output clock signal format (LVPECL, LVDS, CML, CMOS), output phase adjustment
between output clocks, and output phase adjustment between all output clocks and the selected reference input
clock (phase increment/decrement). For more details, consult the Silicon Laboratories timing products website at
www.silabs.com/timing.
Both evaluation boards (EVBs) have a Silicon Laboratories MCU (C8051F340) that supports USB communications
with a PC host. For the pin controlled parts (Si5365 and Si5366), the pin settings of the devices are determined by
the MCU and the PC resident software that is provided with the EVB. For the MCU controlled parts (Si5367 and
Si5368), the devices are controlled and monitored through the serial port (either SPI or I2C). A CPLD sits between
the MCU and the Any-Rate Precision Clock device that performs voltage level translation and stores the pin
configuration data for the pin controlled devices. Jumper plugs are provided so that the user can bypass the MCU/
CPLD to manually control the pin controlled devices. Ribbon headers and SMA connectors are included so that
external clock in, clock out and status pins can be easily accessed by the user. For the MCU controlled devices
(Si5367 and Si5368), the user also has the option of bypassing the MCU and controlling the parts from an external
serial device. On-board termination is included so that the user can evaluate either single-ended or differential as
well as ac or dc coupled clock inputs and outputs. A separate DUT (device under test) power supply connector is
included so that the Any-Rate Precision Clocks can be run at either 1.8 or 2.5 V, while the USB MCU remains at
3.3 V. LEDs are provided for convenient monitoring of key status signals.
For more detailed information about these devices, refer to the Any-Rate Precision Clock Family Reference
Manual.

4. Si5365/66-EVB and Si5367/68-EVB Quick Start
1. Install the Precision Clock EVB Driver. (This must be installed before the EVB is connected to the PC via the
USB cable.) For details, see Section "7.EVB Software Installation" on page 11.
2. Install the Precision Clock EVB Software. (Assumes that Microsoft .NET Framework 1.1 is already installed.)
3. Connect the two power supplies to the EVB. One is 3.3 V and the other is either 1.8 or 2.5 V. The DUT is
powered by the 1.8/2.5 V supply.
4. Turn on the power supplies.
5. Connect a USB cable from the EVB to the PC where the software was installed.
6. Install USB driver.
7. Launch software by clicking on Start→Programs→Silicon Laboratories→Precision Clock EVB Software
and selecting one of the programs.
5. Functional Description
The Si5365/66-EVB, Si5367/68-EVB, and software allow for a complete and simple evaluation of the functions,
features, and performance of the Si5365, Si5366, Si5367 and Si5368 Any-Rate Precision Clocks.
5.1. Narrowband versus Wideband Operation
This document describes two evaluation boards: one for the Si5365 and Si5366 and the other for the Si5367 and
Si5368. The former evaluation board is for pin controlled clock parts and the latter is for clock parts that are to be
controlled by an MCU over a serial port. Each of the two boards supports two parts: one that is wideband (the
Si5365 and the Si5367) and the one that is narrowband (the Si5366 and the Si5368). The narrowband parts are
both capable of operating in the wideband mode, so evaluation of the wideband parts can be done by using a
narrowband part in wideband mode. As such, these evaluation boards are only populated with narrowband parts.
To evaluate Si5365 device operation using the Si5365/66-EVB, the RATE[1:0] pins must be set to LL using the
jumper provided. To evaluate Si5367 device operation using the Si536768-EVB, the Precision Clock EVB Software
should be configured for wideband mode. For details, see the Precision Clock EVB Software documentation that
can be found on the enclosed distribution CD.
When operating in wideband mode (Si5365 and Si5367), the reference oscillator should be disabled because it
could add to the phase noise of the output. Removing R28 will disable the reference oscillator. Installing R50 and
C39 will guarantee that the oscillator will not amplify stray signals.
5.2. Block Diagram
Figure 2 is a block diagram of the evaluation board and it is helpful to refer to this diagram. The MCU
communicates to the host PC over a USB connection. The MCU controls and monitors the Si536x through the
CPLD. The CPLD, among other tasks, translates the signals at the MCU voltage level of 3.3 V to the Si536x's
voltage level, which is nominally 2.5 or 1.8 V. The user has access to all of the Si536x's pins using the various
jumper settings as well as through the host PC via the MCU and CPLD.

5.3. Si536x Input and Output Clocks
The Si536x has four differential inputs that are ac terminated to 50 Ω and then ac coupled to the part. Single ended
operation can be implemented by simply not connecting to one of the two of the differential pairs.
The four clock outputs are all differential, ac coupled and configured for driving 50 Ω transmission lines. When
using single ended outputs, it is important that the unused half of the output be terminated. Given that the
Frame Sync signal can have a duty cycle that is far from 50%, the Frame Sync outputs are dc coupled. If the
Frame Sync signal is configured for CMOS output, then the two outputs are not complements of one another and
should be wired in parallel so that the output drive current is doubled. To evaluate CMOS level Frame Sync
outputs, a 0 Ω resistor should be installed at R19. Note that for the MCU controlled parts (Si5367 and Si5368), the
Frame Sync output signal format can be configured independently of the other four outputs.
Two jumpers are provided to assist in monitoring the Si536x power. When R36 is removed, J25 can be used to
measure the device current. J18 can be used at any time to monitor the supply voltage at the device.
The Si5366 and Si5368 require that an external reference clock be provided to enable the devices to operate as
narrowband jitter attenuators with loop bandwidths as low as 60 Hz. The external reference clock can be either a
crystal, a stand-alone oscillator or some other clock source. The range of acceptable reference frequencies is
described in the Any-Rate Precision Clocks Family Reference Manual (Si53xx-RM). The EVB's are shipped with a
3rd overtone 114.285 MHz crystal that is used in the majority of applications. J1 and J2 are used when the Si536x
is to be configured in narrowband mode with an external reference oscillator (i.e. without using the 114.285 MHz
crystal). When operating in wideband mode, the reference oscillator should be disabled and so that it cannot add to
the output phase noise.
The RATE pins should also be configured for the desired mode, either through DSPLLsim or using the jumper
plugs at J17 (see Table 7).
Table 2 shows how the various components should be configured for the three modes of operation:

R51 is provided so that a different termination scheme can be used. If R51 is populated, then remove R52 and R24.
5.4. CPLD
This CPLD is required for the MCU to control the Si536x over a flexible 1.8 or 2.5 V VDD. The CPLD provides two
main functions: it translates the voltage level from 3.3 V (the MCU voltage) to the Si536x voltage (either 1.8 or
2.5 V). The MCU communicates to the CPLD with the SPI signals SS_CPLD_B (slave select), MISO (master in,
slave out), MOSI (master out, slave in) and SCLK. The MCU can talk to CPLD-resident registers that are
connected to pins that control the Si536x's pins, mainly for pin control mode. When the MCU wishes to access a
Si536x register, the SPI signals are passed through the CPLD, while being level translated, to the Si536x. The
CPLD is an EE device that is retains its code that is loaded through the JTAG port (J32). The core of the CPLD
runs at 1.8 V, which is provided by voltage regulator U4. The CPLD also logically connects many of the LEDs to the
appropriate Si536x pins.

Si5367/68-EVB
5.5. MCU
The MCU communicates with the PC over USB so that PC resident software can be used to control and monitor
the Si536x. The USB connector is J6 and the debug port, by which the MCU is flashed, is J31. The reset switch,
SW1, resets the MCU, but not the CPLD. The MCU is a self-contained USB master and runs all of the code
required to control and monitor the Si536x, both in the MCU mode and in the pin-controlled modes.
U3 contains a unique serial number for each board and U5 is an EEPROM that is used to store configuration
information for the board. The board powers up in free run mode with a configuration that is outlined in "Appendix—
Powerup and Factory Default Settings" on page 25. For the pin controlled parts (Si5365/66-EVB), the contents of
U5 configure the board on power up so that jumper plugs may be used. If DSPLLsim is subsequently run, the
jumper plugs should be removed before DSPLLsim downloads the configuration to the EVB so that the jumpers do
not conflict with the CPLD outputs. For microprocessor parts, U5 configures the EVB for a specific frequency plan
as described in "Appendix—Powerup and Factory Default Settings" on page 25.
The Evaluation board has a serial port connector (J22) that supports the following:
„
Control by the MCU/CPLD of an Any-Rate part on an external target board.
Control of the Any-Rate part that is on the Evaluation board through an external SPI or I2C port.
For details, see J22 (Table 6).
„
Though they are not needed on this Evaluation Board because the CPLD has low output leakage current, some
applications will require the use of external pullup and pulldown resistors when three level pins are being driven by
external logic drivers. This is particularly true for the pin-controlled parts: the Si5365 and Si5367. Consult the
Si53xx-RM Any-Rate Precision Clock Family Reference Manual for details.
LVPECL outputs will not function at 1.8 V. If the Si536x part is to be operated at 1.8 V, the output format
needs to be changed by altering either the SFOUT pins (Si5365/66) or the SFOUT register bits (Si5367/68).
5.6. Power and 2L Signals
This evaluation board requires two power inputs +3.3 V for the MCU and either 1.8 or 2.5 V for the Any-Rate
Precision Clock part. The power connector is J40. The grounds for the two supplies are tied together on the EVB.
There are sixteen LEDs, as described in Table 3. J14 is a three by 10 pin male header by which the user can
manually set the values of the two-level inputs using jumper plugs connected to either ground (silkscreen labeled
L) or the power supply (labeled H). J8 is a twenty pin ribbon header that brings out all of the status outputs from the
Si536x. Note that some pins are shared and serve as both inputs and outputs, depending on how the device is
configured. For users that wish to remotely access the input and output pins settings with external hardware, J14
and J8 can be connected to ribbon cables.
5.7. 3L Pins
The three-level inputs can all be manually configured by installing jumper plugs at J17, either H or L. The M level is
achieved by not installing a jumper plug at a given location. J17 can also be used as a connection to an external
circuit that controls these pins. J22 is a ten pin ribbon header that is provided so that an external processor can
control the Si536x over either the SPI or I2C bus.
