BCM7466

Description

The BCM7466 is a standard definition (SD) satellite, cable, and IP set-top box System-on-Chip solution. BCM7466 combines a fast 550-DMIPS MIPS32/MIPS16e™-class CPU, high-speed 2D graphics processing, including video scaling and motion adaptive deinterlacing, a very flexible data transport processor, an MPEG-4/VC-1/MPEG-2/AVS-compliant video decoder, a programmable audio decoder, three video DACs, stereo high-fidelity audio DACs, a Fast Ethernet port with integrated PHY, dual USB 2.0, a high-speed 800-MHz DDR2 memory controller, and a peripheral control unit that provides a variety of set-top box control functions. Integrated in 65 nm technology, the BCM7466 offers one of the highest levels of single-chip system performance available for STB applications.

The MPEG-2 DVB-compliant transport stream/PES parser and demultiplexer of BCM7466 is capable of simultaneously processing 255 PIDs via 255 PID channels in up to two independent external transport stream inputs and three internal playback channels. All 255 PID channels can be used by the record, audio, and video interface engine (RAVE) and PCR processing. The data transport module supports up to 128 PID channels for message or generic PES processing and storage in up to 128 external DRAM message buffers. The data of BCM7466 transport can be configured to support three playback and two record channels for PVR functionality.
