AN2050FB
CCD Monochrome Video Camera Signal Processor IC
s
Overview
The AN2050FB is an integrated circuit specified to
the monochrome CCD image element which is em-
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.
