| NEC's GENERAL PURPOSE 5 V UPC3221GV AGC AMPLIFIER FEATURES * ON-CHIP LOW DISTORTION AMPLIFIER: IIP3 = +2.5 dBm at minimum gain * WIDE AGC DYNAMIC RANGE: GCR = 50 dB TYP * ON-CHIP VIDEO AMPLIFIER: VOUT = 1.0 VP-P at single-ended output * SUPPLY VOLTAGE: VCC = 5 V * PACKAGED IN 8 PIN SSOP SUITABLE FOR SURFACE MOUNTING * LOW NOISE FIGURE: 4.2 dB TYP INTERNAL BLOCK DIAGRAM AND PIN CONFIGURATION VCC 1 AGCAMP VideoAMP 8 GND1 IN1 IN2 2 3 AGC Cont. PACKAGE OUTLINE S08 8 7 6 5 7 OUT1 6 5 OUT2 GND2 VAGC 4 DESCRIPTION Nec's UPC3221GV is a Silicon Monolithic IC designed for use as an AGC Amplier for digital CATV, cable modem and IP telephony systems. This IC consists of a two stage gain control amplier and a xed gain video amplier. 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 fT NESAT AL silicon bipolar process. This process uses silicon nitride passivation 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 ensure the highest reliability and performance. 3221 N 1 2 3 3.0 MAX 4 All dimensions are typical unless specied otherwise.
