The LM98501 is a CCD signal processor for electronic 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 electronic titling and video overlay. The 10-bit A/D converter preserves the image quality with excellent noise performance.
The LM98501 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.
