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.
FEATURES
Low distortion
: IM3 = 53.5 dBc TYP. @ single-ended output, Vout = 105dB V 0.5 VP-P)/tone
Low noise figure
: NF = 5.0 dB TYP. @ Maximum Gain
Wide AGC dynamic range : GCR = 61 dB TYP. @ input prescribe
On-chip video amplifier : Vout = 1.0 VP-P TYP.@ single-ended output
Supply Voltage
: VCC = 5.0 V TYP.
Packaged in 8-pin SSOP suitable for surface mounting.
APPLICATIONS
Digital terrestrial TV
Digital CATV
Cable modem receivers
