n 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.
n Features
• Frequency characteristics:10MHz (icompatible with
the CCD image element of 330,000 pixels)
• AGC range:18dB (improved SN ratio)
• Operating supply voltage range:4.5V to 5.3V (typ.
5V)
• Power consumption:typ. 225mW
