SDA9206 Datasheet, PDF (7/54 Pages) Siemens Semiconductor Group – ADC with Built in Antialiasing filter and Clock generation UnitS

SDA 9206
• I²C-Bus interface
• P-MQFP-64-3
• 5 V supply voltage for input signals
• 3.3 V or 5 V supply voltage for output signals
1.2 General Description
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 µm CMOS process
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
and pulse generator
• Clock generator with discrete timing oscillator, D/A converter,
analog PLL and divider, as well as a crystal oscillator
