GENERALDESCRIPTION

The XRD9859 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), 8-bit digitally Program-

mable Gain Amplifier (PGA), 10-bit Analog-to-Digital

Converter (ADC) and improved digitally controlled

blacklevelauto-calibrationcircuitrywithpixelaverager

hot pixel clipper, and a DNS filter.

Theautocalibrationcircuitcompensatesforanyinter-

nal offset of the XRD9859 as well as black level offset

from the CCD.

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

theirapplications.

The Correlated Double Sampler (CDS) subtracts the

CCD output signal black level from the video level.

Common mode signal and power supply noise are

rejected by the differential CDS input stage.

The XRD9859 has direct access to the ADC input for

digitizing other analog signals. The XRD9859 is

packaged in 28-lead surface mount SSOP to reduce

space and weight, and is suitable for hand-held and

portableapplications.

The PGA is digitally controlled with 8-bit resolution on

a linear dB scale, resulting in a gain range of 6dB to

38dB with 0.125dB per LSB of the gain code.
