The RF3322 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 sleep mode via the serial control bus. The

device operates over the frequency band of 5MHz to

65MHz for use in current U.S. and European systems.

The amplifier delivers up to 60dBmV at the output of the

balun. Gain is controllable in accurate 1dB steps. The

device is provided in an industry-standard QSOP-20

package.

• Single 5V Supply

• Differential Input and Output

• -30dB to +28dB Voltage Gain Range
