New multi-format HD satellite set-top box single-chip system (Broadcom)
This article refers to the address: http://
Broadcom has released a new multi-format HD satellite set-top box single-chip system that will help manufacturers develop low-cost satellite set-top boxes with personal video recording capabilities (PVR).Broadcom's newest satellite single-chip system is manufactured on a 65-nanometer process with the highest level of functionality, fully integrated with dual tuner/demodulators and the latest generation of AVC (Advanced Video Coding) decoders supporting multiple video formats. By reducing the number of components required to develop set-top box products, Broadcom reduces power consumption by more than 50% over competing solutions, reducing bill of materials and reducing the design of next-generation satellite set-top boxes with "read and write" capabilities. Complexity and product size.
The product released today is the satellite single-chip system solution BCM7335, which provides PVR functionality, supports direct broadcast satellite set-top boxes (DBS) in compliance with DVB-S2, DVB-S and 8PSK global standards, and is backward compatible with the DVB-S standard. Based on Broadcom's previous generations of digital cable and satellite set-top box chips and technologies, service providers have adopted BCM7335-centric set-top boxes that will provide advanced HDTV images to their users at a reasonable cost. , high quality pictures and PVR features.
The BCM7335 is Broadcom's next-generation satellite set-top box monolithic system built on a 65-nanometer process. It combines the dual tuner/demodulator functionality of the BCM4506 satellite front-end chip with the latest generation AVC decoder supporting multiple video formats.
The BCM7335 runs at a 450MHz dual-threaded MIPSTM CPU core and delivers over 950DMIPS of performance. The BCM7335 is designed to support UMA and non-UMA memory architectures and utilizes a 400MHz clock, 32 + 16-bit wide DDR2 memory interface to increase performance and reduce memory costs.
The BCM7335 supports a variety of TV on-chip output interfaces, including HDMI, composite video, component or S-Video output. It also combines Broadcom's advanced 2D graphics engine to take full advantage of its storage and bandwidth for true broadcast quality text and graphics.
The BCM7335 is designed in a 65-nanometer process – the most advanced lithography node technology in today's volume semiconductor manufacturing. This process has lower power consumption, smaller size, and higher integration than the 90 nm and 130 nm processes. Due to the extensive and in-depth communication intellectual property that Broadcom has, the shift to 65-nanometer production processes is changing the landscape of competition. Without a range of market-leading integrated solutions, it is difficult for competitors to take full advantage of the benefits of these next-generation manufacturing processes.
The high-definition satellite set-top box single-chip system BCM7335 with personal video recording is currently sampling to early customers. Satellite set-top box manufacturers can request prices.
Broadcom also provides early-stage customers with a fully supported reference design (BCM97335) to ensure cost-effective design and production, and faster time to market. The BCM7335 reference design is based on the BCM97335 set-top box design development platform, and provides all software source code, schematics and PCB Gerber documentation, as well as detailed design information for satellite TV set-top terminal manufacturers.
