This breakthrough system uses industry-standard products from the high volume cable modem market and the satellite direct broadcast satellite (DBS) market and offers industry-leading performance. The system provides for a standards based solution implementing DVB-S/DOCSIS with the option to optimize system operating points using advanced modulation turbo FEC capabilities built into the BCM4500. The BCM4500 advanced modulation design provides 50% more throughput in the same satellite bandwidth at standard QPSK operating points while simultaneously improving BER performance beyond existing levels. A high performance turbo FEC code is implemented with all required RAM on-chip to move system operating points near the theoretical capacity limits. The BCM4500 is a single-chip digital satellite receiver that supports BPSK, QPSK, 8PSK and 16QAM modulations with iteratively (turbo) decoded error correction coding and also receives DVB-S QPSK signals. The BCM4500 also features a simplified, high-level application program interface (API) user interface employing an on-chip microcontroller for all system configuration, acquisition, control and monitoring functions, including an integrated DiSEqCTM 2.0 controller. The BCM3440 is a highly-integrated CMOS satellite tuner designed to operate with the BCM4500. It supports the full 950 to 2150 MHz input frequency range. The BCM3360 provides a modified DOCSIS/EuroDOCSIS 1.0/1.1 media access controller (MAC). The BCM3360 also includes a 140MHz MIPS32TM 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 BCM3360 DOCSIS/EuroDOCSIS 1.0/1. media access controller (MAC) that has been optimized for satellite system performance including integrated PEP and full support for baseline privacy (BPI+) encryption and decryption. Multiple user support includes 16 SIDS in downstream, 16 destination address (DA) perfect match filters, a 256 multicast/unicast filter entry CAM for multicast/unicast hash filters, and 16 independent upstream queues for support of QoS. To enhance operational support, the BCM3360 MAC provides extended network management MIB/diagnostic features. The BCM94555 broadband satellite system modem evaluation system is intended for use by broadband satellite systems engineers for the evaluation of the high performance, standards-based 2-way satellite modem. It is also intended for use by hardware designers and software developers to reduce product design and development time. The simplified user interface gives engineers easy access to various system parameters, allowing them to select optimal settings to match the link budget requirements. Hardware engineers and software developers can use the BCM94555 as a baseline for the final product architecture and also use it as a test and measurement device to verify their final product performance.
