Preliminary Data Sheet BIPOLAR ANALOG INTEGRATED CIRCUIT PC3231GV 5 V AGC AMPLIFIER + VIDEO AMPLIFIER DESCRIPTION The PC3231GV is silicon monolithic IC designed for use as AGC amplifier for digital CATV, cable modem and digital terrestrial systems. This IC consists of gain control amplifier and video amplifier. The package is 8-pin SSOP (shrink small outline package) suitable for surface mount. This IC is manufactured using our 30 GHz fmax UHS0 (Ultra High Speed Process) 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, uniformly and reliability.
