GENERAL DESCRIPTION
The XRD98L59 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
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.
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.
The auto calibration circuit compensates for any inter-
nal offset of the XRD98L59 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
their applications.
The XRD98L59 has direct access to the ADC input for
digitizing other analog signals. The XRD98L59 is
packaged in 28-lead surface mount TSSOP to reduce
space and weight, and is suitable for hand-held and
portable applications.
