BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC3221GV
5 V AGC AMPLIFIER + VIDEO AMPLIFIER
DESCRIPTION
The µPC3221GV is a silicon monolithic IC designed for use as AGC amplifier for digital CATV, cable modem
systems. This IC consists of gain control amplifier and video amplifier.
The package is 8-pin SSOP suitable for surface mount.
This IC is manufactured using our 10 GHz fT NESAT II AL 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.
FEATURES
• Low distortion
: IM3 = 56 dBc TYP. @ single-ended output, Vout = 0.7 Vp-p/tone
• Low noise figure
: NF = 4.2 dB TYP.
• Wide AGC dynamic range : GCR = 50 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
APPLICATION
• Digital CATV/Cable modem receivers
