Preliminary RF3320 CABLE REVERSE PATH PROGRAMMABLE GAIN AMPLIFIER 3 Typical Applications • Euro-DOCSIS/DOCSIS Cable Modems • CATV Set-Top Boxes • Telephony Over Cable • Home Networks • Automotive/Mobile Multimedia • Coaxial and Twisted Pair Line Driver 3 -A- The RF3320 is a variable gain amplifier for use in CATV reverse path (upstream) applications. It is DOCSIS-compliant 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.
