CXA1310AQ
Single Chip Processing for CCD Monochrome Camera
Description
The CXA1310AQ is designed to perform the basic
signal processing in CCD monochrome cameras with
a single chip. This bipolar lC is most suitable for
compact usage and low power consumption.
32 pin QFP (Plastic)
Features
• Processing from CCD output to 75Ω video output
with a single chip
• Wide variable AGC (4 to 32dB Typ.)
• Built-in operational amplifier for AGC loop
• 75Ω line capacitance minimized using sag compensation function
• Variable white clip level realize wide dynamic range
(140 IRE)
