DESCRIPTION
70
Voltage Gain, GV (dB)
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 differential output for noise performance, which eliminates shielding 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/migration. Thus, these ICs have excellent performance, uniformity
and reliability.
NEC's stringent quality assurance and test procedures ensure the highest reliability and performance.

Recommended to use a 0 to 5 V AGC range
for the system and divide this voltage through
a resistive bridge (see evaluation board).
This helps make the AGC slope less steep.
