DESCRIPTION

NEC's UPC3219GV is a Silicon Monolithic IC designed for

use as an AGC Amplifier for digital CATV, cable modem and

IP telephony systems. This IC consists of a two stage gain

control amplifier and a fixed gain video amplifier. The device

provides 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.

This IC is manufactured using NEC's 10 GHz f

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, this

IC has excellent performance, uniformity and reliability.

NEC's stringent quality assurance and test procedures ensure

the highest reliability and performance.

Note:

1. -3dB with respect to 10 MHz gain
