The RF3321 is a variable gain amplifier for use in CATV

reverse path (upstream) applications. It is designed to be

DOCSIS-compliant for use in cable modems. The gain

control covers a 56 dB range and is serially programma-

ble via three-wire digital bus for compatibility with stan-

dard baseband chipsets. Amplifier shutdown and transmit

disable modes are hardware-controlled. The device oper-

ates over the frequency band of 5MHz to 65MHz for use

in current U.S. and European systems. The amplifier

delivers up to +69dBmV at the output of the balun. Gain

is controllableinaccurate1dB steps. Thedeviceispro-

vided in a thermally enhanced, exposed die flag package.
