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 Low noise figure On-chip video amplifier Supply Voltage : IM3 = 53.5 dBc TYP. @ single-ended output, Vout = 105dB V 0.5 VP-P)/tone : NF = 5.0 dB TYP. @ Maximum Gain : Vout = 1.0 VP-P TYP.@ single-ended output : VCC = 5.0 V TYP.
Wide AGC dynamic range : GCR = 61 dB TYP. @ input prescribe
Packaged in 8-pin SSOP suitable for surface mounting.
APPLICATIONS Digital terrestrial TV Digital CATV Cable modem receivers ORDERING INFORMATION (PLAN) Part Number PC3231GV E1 Package Supplying Form Embossed tape 8mm wide. Pin 1 indicates pull-out direction of tape. Qty 1kpcs/reel.
8-pin plastic SSOP (4.45mm(175))
