∫ IC801/IC802 (TB1274AF)
IC for synchronous processing of video and chroma demodulation for PAL/NTSC/SECAM colour TV.
Color demodulation is provided by a high-performance image compensation circuit in the video section, a PAL/
NTSC/SECAM auto discrimination circuit in the chroma section, and a crystal that generates 4.43 MHz, 3.58
MHz and M/N-PAL clock signals.
This IC has a 4-channel YC signal input, 2-channel RGB signal input, and 2-channel chrominance signal input.
It receives main and sub chrominance signals from IC401 (main) and IC402 (sub) and delivers chrominance
signals via one-channel output.
∫ IC803 (CXA2101Q)
IC having a component input integrated with a high-performance image compensation circuit. Equipped with
circuits for processing baseband signals and RGB signals and a 4-channel video switch incorporating an H/V
synchronization signal processing circuit.
Input selection is done by INPUT-SEL (IIC BUS). Y, Pb, Pr and GBR of Ycb, Cr and HD and their H/V
synchronization signals are inputted to input pins of each channel.
Multi-scan facility permits acceptance of a horizontal scan line frequency range of 15 KHz to 60 KHz.
∫ IC1901 (IXA392WJ)
FPGA for synchronous processing
This IC selects synchronization signals and creates horizontal blanking signals.
∫ IC604 (TA1318AF)
IC for synchronous processing of TV component signals and measurement of frequency.
This IC incorporates an input signal frequency measurement feature and synchronous regeneration features.
It supports synchronous horizontal regeneration (15.75 kHz, 31.5 kHZ, 33.75 kHz and 45 kHz) and synchronous
vertical regeneration (525i, 525P, 625i and 750P).
