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 5MHz 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 1dB steps. The device is provided in a thermally enhanced, exposed die flag package.
The RF3320 is a variable gain amplifier designed for use in CATV reverse path (upstream) applications, specifically compliant with DOCSIS standards for cable modems. It features a gain control range of -30dB to +28dB, programmable via a three-wire digital bus. The device operates over a frequency band of 5MHz to 65MHz and delivers up to 60dBmV at the output of the balun. It is available in an exposed die flag package and supports sophisticated power management modes including sleep and software shutdown.
