the BCM3360 combines an advanced phy qam receiver, an advanced phy qam transmitter, a docsis/eurodocsis 1.0/1.1 media access controller (mac) with complete interleaver support for advanced phy, a 140-mhz mips32 processor, an ip security (ipsec) engine, a 16-bit, 100-mhz sdram interface, 10/100 ethernet mac with integrated transceiver and mii interface, a usb 1.1 controller with integrated transceiver, an hpna 2.0 mac and support for extended devices through an ebi interface. the qam receiver directly samples a tuner output with a 10-bit a/d converter and input acg amplifier. the receiver digitally resamples and demodulates the signal with recovered clock and carrier timing, filters and equalizes the data, and passes soft decisions to an itu-t j.83 annex a/b/c compatible decoder. a 40-tap adaptive decision feedback equalizer is implemented. the receiver supports variable symbol rate 64/256 qam fec decoding. the final received data stream is delivered in a serial mpeg-2 transport format. all gain, clock, and carrier, acquisition and tracking loops are integrated in the qam receiver. the upstream transmitter takes burst or continuous data, provides fec encoding and pre-equalization for docsis/eurodocsis applications, filters and applies qpsk or qam16 modulation to the data stream, amplifies the signal through the integrated upstream power amplifier, and provides a direct 0?5 mhz analog output. the BCM3360 media access controller (mac) includes all features required for full docsis/eurodocsis 1.0/1.1 compliance, including full support for baseline privacy (bpi+) encryption and decryption. multiple user support includes 16 sids in downstream, 16 da perfect match filters, a 256 entry cam for multicast/unicast hash filter and 16 independent upstream queues for simultaneous support of qos and be traffic. to enhance operational support, the BCM3360 mac provides extended network management mib/diagnostic features, as well as immediate ucc (on the fly) using independent resets for downstream and upstream and both individual queue reset/flush for upstream queues. the BCM3360 uses advanced propane techniques to provide packet acceleration to significantly improve upstream channel utilization. the BCM3360 is the first single-chip cable modem that supports the fa-tdma advanced phy technology. in addition, the BCM3360 supports advanced qam rates for higher performance and at the same time offers better performance in noisy plants. with on-chip hpna support, combined with the ebi support for wireless cpe interface, the BCM3360 provides the ideal platform for a home gateway cable modem. ordering information: BCM3360 kpb docsis/eurodocsis applications BCM3360 overview 140mhz mips32 core with mmu timers uart interrupt control 8kb i-cache 4kb d-cache dma gpio usb 1.1 if tuner ctl leds/ misc 100mhz internal system bus BCM3360 pb bridge 100base-tx 802.3u mii hpna 2.0 afe filter tuner coax rf peripheral bus 802.3u ethernet mac usb 1.1 mac enhanced docsis/ eurodocsis 1.0/1.1 mac with bpi+ iline20 hpna 2.0 mac 16/32-bit sdram interface 100mhz sdram qpsk/16/64/ 256qam upstream modulator 1024qam downstream demodulator usb 1.1 transceiver jtag clock generation 10/100mb enet transceiver upstream power amp ipsec encryption engine 16-bit external bus interface flash phone: 949-450-8700 fax: 949-450-8710 email: info@broadcom.com web: www.broadcom.com broadcom , the pulse logo , qamlink , propane tm and connecting everything tm are trademarks of broadcom corporation and/or its subsidiaries in the united states and certain other countries. all other trademarks are the property of their respective owners. broadcom corporation 16215 alton parkway, p.o. box 57013 irvine, california 92619-7013 ? 2002 by broadcom corporation. all rights reserved. 3360-pb03-r-4.24.02
