GENERALDESCRIPTION

The XRD98L63 is a complete, low power CCD Image

Digitizer for digital motion and still cameras. The

product includes a high bandwidth differential Corre-

lated Double Sampler (CDS), 10-bit Programmable

GainAmplifier(PGA)withpixelrategainswitching,12-

bit Analog-to-Digital Converter (ADC) and improved

digitallycontrolledblacklevelauto-calibrationcircuitry

with programmable pixel averaging, hot pixel clipping,

and a Digital Noise Suppression (DNS) filter.

desired gain ratios for color balance. The system gain

can then be changed by writing to a single register,

and the color balance will be maintained.

The black level auto-calibration circuit averages the

results of the Optical Black pixels to compensate for

any internal offset of the XRD98L63 as well as black

level offset from the CCD. The calibration logic uses

proprietary digital filters to eliminate line-to-line offset

noise and noise due to hot pixels in the Optical Black

areas.

The Correlated Double Sampler (CDS) subtracts the

CCD output signal black level from the video level.

Commonmodeandpowersupplynoisearerejectedby

the differential CDS input stage.

The PGA and black level auto-calibration are con-

trolled through a simple 3-wire serial interface. The

timing circuitry is designed to enable users to select a

wide variety of available CCD and image sensors for

their applications. Readback of the serial data regis-

ters is available from the digital output bus.

programmed to switch gain every pixel, in a user
