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 1.0 MSPS to 10.0 MSPS per channel for 3 -Channel mode and up to 15.0 MSPS in single channel mode.
Pixel-by-Pixel Offset and Gain control through a parallel interface running at a maximum 60 Mbyte/sec. ...
