PC3231GV
GENERAL PURPOSE 5 V 100 MHz AGC AMPLIFIER
DESCRIPTION
The PC3231GV is a 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, uniformity and reliability.

NOTES ON CORRECT USE
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired
oscillation).
All the ground pins must be connected together with wide ground pattern to decrease impedance difference.
(3) The bypass capacitor should be attached to VCC line.
