2. TDA15063H introduction:
The third-generator super integrated circuit UOC III which designed by
Philips company recently integrates with video decode2D comb filterhigh
quality audio transacting technique, suitable with the European teletext
technique and suitable with US closed caption and V-chip function compatiable
with single series IC. The series of UOC III have high integraty,besides
completing the Processing of all small signal(IF signal demodulation, video
decode ,H/V signal, sound DSP),and integrate all the MCU function. it has
many Advantages ,example: the compact circuitgood performancesimple
craft , ect. it match with company’s high performance price ratio and high
product efficiency demandings. it is suitable for 4:3 or 16:950/60HZ and
A100/120HZ TV system, the main characteristic below:
 Multi-system IF demodulationanalog video decode
 Comb filter internal
 Support 4:316:9 display format
 4 CVBS or 3 Y/C input,1 CVBS output,2 YcrCb/2 RGB input
