GENERAL PURPOSE 5 V AGC AMPLIFIER
DESCRIPTION
The
µ
PC3217GV,
µ
PC3218GV are silicon monolithic ICs designed for use as AGC amplifier for digital CATV,
cable modem systems. These ICs consist of gain control amplifier and video amplifier.
The package is 8-pin SSOP suitable for surface mount.
These ICs are manufactured using NEC’s 10 GHz f
T
NESAT II AL silicon bipolar process. This process uses
silicon nitride passivation film.
This material can protect chip surface from external pollution and prevent
corrosion/migration. Thus, these ICs have excellent performance, uniformity and reliability.
