1. INTRODUCTION
17MB22 Main Board consists of Micronas concept, VCTP as controller. This IC is
capable of handling Audio processing, video processing, motion adaptive
upconversion(MAU), Scaling-Display processing and FPD control (DPS),unified memory
for audio video and Text, 3D comb filter-PC connectivity , OSD and text processing.
TV supports PAL, SECAM, NTSC colour standards and multiple transmission standards
as B/G, D/K, I/I’, and L/L’ including German and NICAM stereo.
Sound system output is supplying 2x8W (10%THD) for stereo 8Ω speakers.
Supported peripherals are:
1 RF input VHF1, VHF3, UHF @ 75Ohm
1 FAV input
2 SCART sockets
1 SVHS input
1 Stereo Headphone input
1 YPbPr
1 PC input
1 HDMI input
1 Stereo audio input for PC
2. TUNER
As the thickness of the TV set has a limit, a horizontal mounted tuner is used in the
product, which is suitable for CCIR systems B/G, H, L/ L’, I/I’, and D/K. The tuning is
available through the digitally controlled I2C bus (PLL). Below you will find info on the
Tuner in use.
2.1 General description of UV1316:
The UV1316 tuner belongs to the UV 1300 family of tuners, which are designed to meet
a wide range of applications. It is a combined VHF, UHF tuner suitable for CCIR
systems B/G, H, L, L’, I and I’. The low IF output impedance has been designed for
direct drive of a wide variety of SAW filters with sufficient suppression of triple transient.
