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

suited for portable video applications. This low-power processor

is a natural choice for the most demanding imaging systems.
