Exar Corporation XRD98L59
The XRD98L59 is a complete low power CCD Image Digitizer for digital, motion and still cameras. The product includes a high bandwidth differential Correlated Double Sampler (CDS), 8-bit digitally Programmable Gain Amplifier (PGA), 10-bit Analog-to-Digital Converter (ADC) and improved digitally controlled black level auto-calibration circuitry with pixel averager hot pixel clipper, and a DNS filter. The Correlated Double Sampler (CDS) subtracts the CCD output signal black level from the video level.| Part No. | XRD98L59 |

GENERAL DESCRIPTION
Common mode signal and power supply noise are rejected by the differential CDS input stage. 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.
