LM98503 10-Bit, 18 MSPS Camera Signal Processor October 2000 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.
