DESCRIPTION
Nec's UPC3221GV is a Silicon Monolithic IC designed for use as an AGC AmpliÞ er for digital CATV, cable modem and IP telephony systems. This IC consists of a two stage gain control ampliÞ er and a Þ xed gain video ampliÞ er. The device provides a differential input and differential output for noise performance, which eliminates shielding re quire ments. The package is 8-pin SSOP (Shrink Small Outline Package) suitable for surface mount. This IC is manufactured using NEC's 10 GHz f T NESATΙΙ AL silicon bipolar process. This process uses silicon nitride pas si va tion Þ lm. 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 en sure the highest reliability and performance.

Minimuim Gain at V AGC = 0.5 V Maximum Gain at VAGC = 3 to 3.5 V Recommended to use by dividing AGC voltage with external resistor (ex. 1kΩ) 5 GND 2 0 Ground pin. This pin should be con- nected to system ground with minimum inductance. Ground pattern on the board should be formed as wide as possible. 6 OUTPUT2 2.28 Signal output pins of video ampli Þ er 7 OUTPUT1 2.28 8 GND 1 0 Ground pin. This pin should be con- nected to system ground with minimum inductance. Ground pattern on the board should be formed as wide as pos- sible. All ground pins must be connect- ed together with wide ground pattern to decrease impedance difference. PIN EXPLANATIONS 2 5 3 AGC Control AGC Amp Note: 1. PIN is measured at VCC = 5 V UPC3221GV
