DESCRIPTION
NEC's UPC3217GV and UPC3218GV are Silicon Monolithic
ICs designed for use as AGC amplifiers for digital CATV,
cable modems and IP telephony systems. These ICs consist
of a two stage gain control amplifier and a fixed video gain
amplifier. The devices provide a differential input and differ-
ential output for noise performance, which eliminates shield-
ing requirements.
The package is 8-pin SSOP (Shrink Small Outline Package)
suitable for surface mount.
These ICs are manufactured using NEC's 10 GHz fT
NESATΙΙ AL silicon bipolar process. This process uses
silicon nitride passivation film. This material can protect chip
surface from external pollution and prevent corrosion/migra-
tion. Thus, these ICs have excellent performance, uniformity
and reliability.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
