BCM7420

Description

The BCM7420 redefines media center system integration: a MoCA® modem for home networking, 1080p60 quality video, a 1500-DMIPS (Millions of Instructions per Second) CPU, a dual-channel high-definition video decoder (H.264,VC-1, MPEG-2, MPEG-4 Part 2, H.263, and DivX), mosaic video support, a dual-channel multifunction audio decoder, PC class 2D and 3D graphics processing, high-quality video scaling and motion-compensated deinterlacing, seven video DACs, dual-stereo high-fidelity audio DACs, and a suite of peripherals providing a variety of set-top box control functions -all under the oversight of a dynamic power controller for energy efficiency. The BCM7420 supports either DDR2 or DDR3 memory architectures future-proofing the system design. The BCM7420 also contains a programmable security processor and transport engine making the solution perfect for cable, satellite, IP, digital TV and retail business models.

The integrated 1.0/1.1+ MoCA Modem, PHY and on-chip RF transceiver incorporates a 200-DMIPS CPU, 256 QAM for bit loading and an extended frequency range. All flow control and processing of BCM7420 is offloaded from the host processor. Support  of BCM7420 is included for Low-RF mode. The modem is driven by a dedicated on-chip Gbit Ethernet MAC for efficient data transfers and address learning, thereby achieving maximum actual system throughput. When used in conjunction with other Broadcom-enabled devices, additional performance can be realized. The controller is field-programmable, allowing the service provider to tune performance for unique circumstances. When paired with a BCM3450 power amplifier/low-noise filter, BCM7420 forms a direct connection to a MoCA network.
