The SDA 9206 is a single monolithic IC containing three separate 8-Bit A/D converters
for video (YUV) applications and a clock sync generator which is delivering the sample
clock for the A/D converters. It utilizes an advanced VLSI 0.5
providing 30 MHz sampling rates at 8-Bits.
The YUV processing consists of following functional blocks:
• Analog input buffers and clamping circuits
• Three 30 MHz A/D converters
• Digital decimation filters
• Delay compensation in Y-path
• Output formatter and buffer
The clock sync generator consists essentially of the following functional blocks:
• Analog clamping
• 7-Bit A/D converter
• Sync processor with digital horizontal PLL, vertical sync processor
• Clock generator with discrete timing oscillator, D/A converter,
