Exar Corporation XRD9836ACGTR-F

Description
The XRD9836 is a 16-bit analog front-end (AFE) designed for use in 3-channel/1-channel CCD/CIS document imaging applications. It provides pixel-by-pixel gain and offset control for each channel through a time-multiplexed parallel input. The outputs from each channel are transmitted time-multiplexed, with the high-order byte followed by the low-order byte for red, blue, and green.

Features
16-bit resolution ADC with a 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 data rate
A microprocessor serial port to control various modes of operation
Fixed Gain/Offset Mode (FGOM) or Pixel by Pixel Gain/Offset Mode (PPGOM)
Alternate Pixel Offset Adjust Mode (APOAM)
Low Power CMOS - 280mW (typ. 3V); Power-Down Mode - 1mW (typ. @ 3V with static clocks)
Single Power Supply (3.0 to 3.6 Volts) with Max CCD input signal of 1V and reset pulse up to 0.5V
High ESD Protection: 2000 Volts Minimum

Applications
Scanners
Multi-Function Printers (MFPs)
