Preliminary RF3321 REVERSE PATH HIGH OUTPUT POWER PROGRAMMABLE GAIN AMPLIFIER 2 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 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 56dB range and is serially programmable via three-wire digital bus for compatibility with standard baseband chipsets. Amplifier shutdown and transmit disable modes are hardware-controlled. The device operates over the frequency band of 5MHz to 65MHz for use in current U.S. and European systems.
