1. INTRODUCTION
1.1 Purpose
This manual provides the information necessary to repair, calibration, description and download the
features of the KM380t Series.
1.2 Regulatory Information
A. Security
Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example,
persons other than your company’s employees, agents, subcontractors, or person working on your
company’s behalf) can result in substantial additional charges you’re your telecommunications
services. System users are responsible for the security of own system. There are may be risks of toll
fraud associated with your telecommunications system. System users are responsible for
programming and configuring the equipment to prevent unauthorized use. LGE does not warrant that
this product is immune from the above case but will prevent unauthorized use of common-carrier
telecommunication service of facilities accessed through or connected to it. LGE will not be
responsible for any charges that result from such unauthorized use.
B. Incidence of Harm
If a telephone company determines that the equipment provided to customer is faulty and possibly
causing harm or interruption in service to the telephone network, it should disconnect telephone
service until repair can be done. A telephone company may temporarily disconnect service as long as
repair is not done.
C. Changes in Service
A local telephone company may make changes in its communications facilities or procedure. If these
changes could reasonably be expected to affect the use of the KM380t Series or compatibility with the
network, the telephone company is required to give advanced written notice to the user, allowing the
user to take appropriate steps to maintain telephone service.
D. Maintenance Limitations
Maintenance limitations on the KM380t Series must be performed only at the LGE or its authorized
agents. The user may not make any changes and/or repairs expect asspecifically noted in this manual.
Therefore, note that unauthorized alternations or repair may affect the regulatory status of the system
and may void any remaining warranty.

E. Notice of Radiated Emissions
The KM380t Series complies with rules regarding radiation and radio frequency emission as defined
by local regulatory agencies. In accordance with these agencies, you may be required to provide
information such as the following to the end user.
F. Pictures
The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly
different.
G. Interference and Attenuation
An KM380t Series may interfere with sensitive laboratory equipment, medical equipment, etc.
Interference from unsuppressed engines or electric motors may cause problems.
H. Electrostatic Sensitive Devices
ATTENTION
Boards, which contains Electrostatic Sensitive Device(ESD), are indicated by the sign.
Following information is ESD handling: Service personnel should ground themselves by using a wrist
strap when exchange system boards.
When repairs are made to a system board, they should spread the floor with anti-static mat which is
also grounded. Use a suitable, grounded soldering iron. Keep sensitive parts in these protective
packages until these are used. When returning system boards or parts such as EEPROM to the
factory, use the protective package as described.

Input ON is a power-on input for S-GOLDradio with 2 active high levels (see Figure 8). It might be
triggered by a push button. To detect if the push-button is pressed during system operation the logical
level at pin ON or its change (if Bit 1 EION in INTCTRL2 is asserted) is recorded in bit LON of the ISF
register. If the high level of voltage at pin ON does not reach VIHdet (Vbat-0.8 ~ Vbat-0.3) the abovementioned bit won’t be set.
To support Remote power on function for factory mass production, applied an BJT as following figure.
As monitoring the RPWRON and Key matrix KP_OUT(2) & KP_IN(6), KM380t series system recognize
whether remote power on or End-key pushed

3.11 LCD back light illumination
MAX8630W is a charge pump designed to support PWM control mode. And MAX8630W supports 5
white LEDs. The MAX8630W is capable of driving up to 5 LEDs at a total of 100mA(MAX8630W
100mA).
The current sinks may be operated individually or in parallel for driving higher current LEDs. To
maximize power efficiency, the charge pump operates in 1X, 1.5X, or 2X mode, where the mode of
operation is automatically selected by comparing the forward voltage of each LED with the input
voltage.

4.2 Receiver part
Figure 29. PMB 6272 Function Block Diagram
The constant gain direct conversion receiver contains all active circuits for a complete receiver chain
for GSM/GPRS/EDGE (see Figure 30). The GSM850/900/DCS1800/ PCS1900 LNAs with balanced
inputs are fully integrated. No inter-stage filtering is needed. The orthogonal LO signals are generated
by a divider-by-four for GSM850/900 band and a divider-by-two for the DCS1800/PCS1900 band.
Down conversion to baseband domain is performed by low/high band quadrature direct down
conversion mixers. The baseband chain contains a LNB (low noise buffer), channel filter, output buffer
and DC-offset compensation. The 3rd order low pass filter is fully integrated and provides sufficient
suppression of blocking signals as well as adjacent channel interferers and avoids anti-aliasing
through the baseband ADC. The receive path is fully differential to suppress on-chip interferences.
Several gain steps are implemented to cope with the dynamic range of the input signals. Depending
on the baseband ADC dynamic range, single- or multiple gain step switching schemes are applicable.
Furthermore an automatic DC-offset compensation can be used (depending on the gain setting) to
reduce the DC-offset at baseband-output. A programmable gain correction can be applied to correct
for front end- and receiver gain tolerances.

4.3 Transmitter part
The GMSK transmitter supports power class 4 for GSM850 and GSM900 as well as power class 1 for
DCS1800 and PCS1900. The digital transmitter architecture is based on a very low power fractional-N
Sigma-Delta synthesizer without any external components (see Figure39). The analog I/Q modulation
data from the baseband is converted to digital, filtered and transformed to polar coordinates. The
phase/frequency signal is further on processed by the Sigma-Delta modulation loop. The output of its
associated VCO is divided by four or two, respectively, and connected via an output buffer to the
appropriate single ended output pin. This configuration ensures minimum noise level. The 8PSK
transmitter supports power class E2 for GSM850 and GSM900 as well as for DCS1800 and PCS1900.
The digital transmitter architecture is based on a polar modulation architecture, where the analog
modulation data (rectangular I/Q coordinates) is converted to digital data stream and is subsequently
transformed to polar coordinates by means of a CORDIC algorithm. The resulting amplitude
information is fed into a digital multiplier for power ramping and level control. The ready processed
amplitude signal is applied to a DAC followed by a low pass filter which reconstructs the analog
amplitude information. The phase signal from the CORDIC is applied to the Sigma-Delta fractional-N
modulation loop. The divided output of its associated VCO is fed to a highly linear amplitude
modulator, recombining amplitude and phase information. The output of the amplitude modulator is
connected to a single ended output RF PGA for digitally setting the wanted transmit power. The PA
interface of SMARTi-PM supports direct control of standard dual mode power amplifiers (PA’s) which
usually have a power control input VAPC and an optional bias control pin VBIAS for efficiency
enhancement. In GMSK mode, the PA is in saturated high efficiency mode and is controlled via its
VAPC pin directly by the baseband ramping DAC. In this way both up- / down-ramping and output
power level are set. In 8PSK mode, the ramping functionality is assured by an on-chip ramping
generator, whereas output power is controlled by the PGA’s as described above.

4.4 RF synthesizer
The transceiver contains a fractional-N sigma-delta synthesizer for the frequency synthesis in the RX
operation mode. For TX operation mode the fractional-N sigma-delta synthesizer is used as SigmaDelta modulation loop to process the phase/frequency signal. The 26MHz reference signal is provided
by the internal crystal oscillator. This frequency serves as comparison frequency of the phase detector
and as clock frequency for all digital circuitry.The divider in the feedback path of the synthesizer is
carried out as a multi-modulus divider (MMD). The loop filter is fully integrated and the loop bandwidth
is about 100 kHz to allow the transfer of the phase modulation. The loop bandwidth is automatically
adjusted prior to each slot (OLGA©˜). To overcome the statistical spread of the loop filter element
values an automatic loop filter adjustment (ALFA) is performed before each synthesizer startup. The
fully integrated quad-band VCO is designed for the four GSM bands (850, 900, 1800, 1900 MHz) and
operates at double or four times transmit or receive frequency. To cover the wide frequency range the
VCO is automatically aligned by a binary automatic band selection (BABS) before each synthesizer
startup.

4.5 DCXO
The transceiver contains a fully integrated 26MHz digitally controlled crystal oscillator (DCXO) with
three outputs for the system clock, one output for the GSM baseband and two additional for other
subsystems (GPS, Bluetooth, etc.). The only external part of the oscillator is the crystal itself. The
overall pulling range of the DCXO consists of eight subranges. The subrange closest to the ‘0ppm’ at
the middle AFC-value is selected during the calibration process in the mobile’s production and is used
for the rest of the lifetime. The frequency tuning is performed along the selected subrange by
programming the frequency control word (XO_TUNE) via the three wire bus (“3Wbus”).
4.6 Front End Module control
Implemented in the Transceiver are two outputs for direct control of front end modules with two logic
input pins to select RX- and TX-mode as well as low- and high band operation.
