XRD9836
JUNE 2003
16-BIT PIXEL GAIN AFE
REV. 1.0.0
GENERAL DESCRIPTION
The XRD9836 is a precision 16-bit analog front-end (AFE) for use in 3-channel/1-channel CCD/CIS document imaging applications. Pixel-by-pixel gain and offset for each of the 3 channels are controlled using a time multiplexed parallel input. Offset and Gain are sequentially supplied for red, green, and blue. The outputs from each of the three channels are transmitted time multiplexed with the high order byte first followed by the low order byte for red, blue and green.
FEATURES
• 16-bit resolution ADC, 30MHz Sampling Rate
• 10-bit accurate linear programmable gain range selectable as either 2-to-20 V/V or 1-to-10 V/V per channel
• Fully-differential input pins and internal path
• Sampling rates from 1.
