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 065 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.
