DESCRIPTIONꢀ
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 con-
sist of a two stage gain control amplifier and a fixed video
gain amplifier. The devices provide a differential input and
differential output for noise performance, which eliminates
shielding requirements.
UPC3218GV
The package is 8-pin SSOP (Shrink Small Outline Package)
suitable for surface mount.
These ICs are manufactured using NEC's 10 GHz fT
NESATΙΙ 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, theseICshaveexcellentperformance, uniformity
and reliability.
