3-CHANNEL 16-BIT LINEAR CCD/CIS SENSOR SIGNAL PROCESSOR

JUNE 2004

REV. 1.0.1

GENERAL DESCRIPTION

FEATURES

The XRD9818 is a fully integrated, high-performance

analog

signal

processor/digitizer

specifically

· 16-Bit A/D Converter

designed for use in 3-channel/2-channel/1-channel

CCD/CIS document imaging applications.

· Triple-Channel, 4MSPS Color Scan Mode

· Single-Channel, 8MSPS Monochrome Scan Mode

· Multiplexed 8-Bit or 4-Bit Output Data Formats

· Triple Correlated Double Sampler

· Triple 9-Bit Programmable Gain Amplifier

· Two Programmable Gain Ranges

· Triple 10-Bit Offset Compensation DAC

· -280mV to +380mV Offset Compensation

· 28-pin TSSOP Package

Each channel of the XRD9818 includes a Correlated

Double Sampler (CDS), Offset adjustment,

Programmable Gain Amplifier (PGA). After the gain

and offset adjustments the analog inputs are

sequentially sampled and digitized by a 16-bit A/D

converter. The digital output data is available in 8 or

4-bit wide multiplexed format.

The analog front-end can be configured for use in

CCD or CIS data acquisition applications. The CDS

mode of operation supports both line and pixel-clamp

modes and can be used to achieve significant

reduction in system 1/f noise and CCD reset clock

feed-through. Five programmable clamp levels are

available in CCD mode to adjust for CCD signal swing

and reset pulse size. For CIS mode there are 3

selectable reference options, two internally generated

and one external applied reference.

· Internal Voltage Reference

· 3V Operation with 5V Tolerant inputs

· Low Power CMOS: 190mW @ 3.3V (typ),

Down 1mW (typ)

Power

APPLICATIONS

Two PGA ranges, programmable through the serial

port, help interface the XRD9818 to CCD imagers

that have either a 3V or 2V output swings. The range

of 1x to 5x is used for 3V inputs and the range of 1.5x

to 7.5x is used for 2V inputs. Each channel has an

offset range of -180mV to 180mV (1.4mV/step) for

fine adjustment and an additional -100mV to 200mV

(100mV/step) of gross offset adjustment to correct for

any system offsets.

· 48-Bit Color Scanners

· High-performance CCD or CIS Color Scanners

· Multifunction Peripherals

· Film Scanners
