AN2050FB
CCD Monochrome Video Camera Signal Processor IC
■ Overview
Unit:mm
The AN2050FB is an integrated circuit specified to
10.0±0.3
33
23
the monochrome CCD image element which is em-
34
22
ployed in the monitoring video cameras, door phones,
TV telephone sets, etc. The high frequency block and
power block that are composed of 3-chip of DS signal
processing, AGC. Γ compensating and NTSC output
so far, are integrated into one chip to offer low cost.
