SDA 9205-2 Q67100-H5069 P-LCC-68-1 (SMD)
General Description
The SDA 9205-2 is a single monolithic IC containing three separate 8-bit analog to digital converters
for video (YUV) applications. It utilizes an advanced VLSI 1.2 um CMOS process providing 30-MHz
sampling rates at 8 bits. Different digital output multiplex formats are selectable on chip via several
control inputs, compatible to inputs of all Siemens Featureboxes, Siemens TV-SAM, and CCIR 656
output format.
The ADCs have no missing codes over the full operating temperature range of 0 to + 70 °C.
Operation is from + 5 V DC-power supply.
