LM98503
10-Bit, 18 MSPS Camera Signal Processor
General Description
The LM98503 is a CCD signal processor for digital cameras.
The processor provides a common interface to a number of
different image sensors including CCD, CMOS, and CIS.
Correlated double sampling reduces kTC noise from the image
signal. A fast, temperature stable, 8-bit digitally programmable
gain amplifier enables pixel-rate white-balancing. An auxiliary
input is provided, allowing for the selection of an external signal,
useful for sampling analog video signals. The 10-bit A/D
converter preserves the image quality with excellent noise
performance. The LM98503 also includes the supporting
functions of digital black level clamp and power down, ideally
is a natural choice for the most demanding imaging systems.
