3. TUNER
Either a PLL or a VST tuner is used as a tuner.
UV1316 (VHF/UHF) is used as a PLL tuner. For only PAL M/N, NTSC M applications UV 1336 is used as the PLL tuner.
UV 1315 (VHF/UHF) is used as a VST Tuner.

4. MULTISTANDARD SOUND PROCESSOR
The MSP 34xxG is designed to perform demodulation of FM or AM-Mono TV sound. Three kinds of MSP’s are used:
MSP 3400G,MSP 3410G and MSP 3411G. The MSP 3400G is fully pin and software-compatible to the MSP 3410G,
but is not able to decode NICAM. It is also compatible to the MSP 3411G,sound processor IC with virtual dolby sound.
5. SOUND OUTPUT STAGETDA7269A
The TDA7269A is a class AB dual Audio power amplifier, specially designed for high quality sound applications as
Hi-Fi music centers and TV sets. It is supplied by ±12VDC coming from two separate windings in the SMPS transformer.
It gives 2x14W(THD=10%) output power into an 8ohm load.
6. VERTICAL OUTPUT STAGE WITH STV9306
The STV9306 is a fully I
2
C controlled vertical deflection IC designed for use in 110°, 4/3 or 16/9 CRT applications.
It integrates both the vertical deflection and E/W correction circuitries necessary in design of a 110° chassis.
