The RF3320 is a variable gain amplifier for use in CATV

reverse path (upstream) applications. It is DOCSIS-com-

pliant for use in cable modems. The gain control covers a

58dB range and is serially programmable via three-wire

digital bus for compatibility with standard baseband

chipsets. Amplifier shutdown and transmit disable modes

are software- and hardware-controlled. The device is

placed into software-shutdown mode via the serial control

bus. The device operates over the frequency band of

5 MHz to 65MHz for use in current U.S. and European

systems. The amplifier delivers up to 60dBmV at the out-

put of the balun. Gain is controllable in accurate 1 dB

steps. The device is provided in a thermally enhanced,

exposed die flag package.
