GND1 PACKAGE OUTLINE S08 DESCRIPTION 6 5 3221 The package is 8-pin SSOP (Shrink Small Outline Package) suitable for surface mount. N This IC is manufactured using NEC's 10 GHz fT NESATΙΙ AL silicon bipolar process. This process uses silicon nitride passivation Þlm. 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. 7 8 Nec's UPC3221GV is a Silicon Monolithic IC designed for use as an AGC AmpliÞer for digital CATV, cable modem and IP telephony systems. This IC consists of a two stage gain control ampliÞer and a Þxed gain video ampliÞer. The device provides a differential input and differential output for noise performance, which eliminates shielding requirements. 1 2 3 3.0 MAX 4 All dimensions are typical unless speciÞed otherwise.
