BCM7335：High-Definition PVR Satellite System-on-Chip The BCM7335 is Broadcom’s next-generation satellite PVR set-top box system on a single chip in 65-nm process. It integrates the dual-tuner/ demodulator BCM4506 front-end technology and the latest generation of AVC decoder that supports multiple video formats. The BCM7335 supports worldwide standards for DBS transmission systems based on DVB-S2, 8PSK, and is backward compatible with the DVB-S standards. The BCM7335 operates on a dual-threaded MIPS CPU core running at 450-MHz and yielding over 950 DMIPS in performance. The BCM7335 is designed to support UMA and non-UMA memory architectures, utilizing a 400-MHz clock, 32 + 16-bit wide Double Data Rate (DDR2) memory I/F for enhanced performance and allows cost-effective memory solutions. The BCM7335 is a true single chip that can decode transport streams delivered via the integrated DBS front ends. In addition, it is capable of decoding external TS input from 10/100 Ethernet port or via the dual SATA interface for DVR applications with full trick mode support. Several interfaces required for TV output are integrated on-chip including the HDMI, baseband composite, component, or S-Video. An RF channel 3/4 modulated output is also integrated on chip. An HD video encoder with copy protection that supports NTSC, PAL, and SECAM with simultaneous SD output and optional Macrovision/DCS support is integrated on chip as well. The BCM7335 incorporates Broadcom’s advanced 2D graphics engine, offering true studio-quality text and graphics with extremely efficient use of memory and bandwidth. A full range of peripheral devices is supported on the BCM7335, including UARTs, dual ISO7816 smart card interfaces, GPIO, counters/ timers, IR Tx/Rx, UHF Rx, I2C, and SPI controllers. 主要特性： Dual-integrated wide-band silicon tuners with DiSEqC 2.x and programmable FSK transceiver•Integrated demods Dual DVB-S2 8PSK Demods QPSK demod (market-dependant) AVC-compliant video decoder for MPEG-4 Parts 2 and 10, MPEG-2, VC-1, ATSC, DivX, Xvid Programmable decoder supports multiple formats includingMPEG Layers 1 and 2, AC3, AAC, PCM Audio•Multi-threaded MIPS CPU 450 MHz, 32-KB I/D, 128-KB L2 MMU and FPU support, EJTAG debug interface 400-MHz Clock (800-MHz Data) rate DDR2 memory configurable in UMA and non-UMA modes•NAND/NOR flash support Rich 2D graphics based on Broadcom® Graphics Engine Dual SATA-2 with eSATA support Dual 10/100 Ethernet with PHY and MII Three USB 2.0 ports•On-chip Security Processor Low cost DVB-CI support 主要优势： Provides a cost-effective single-chip solution for high-definition Direct Broadcast Satellite (DBS) applications with watch-and-record capabilities. Based on field-proven and production-ready subsystems offering energy-efficient performance. Feature-rich, fully integrated SoC reduces the external components needed and reduces PCB real-estate. Allows cost-effective DDR2-based memory with support for UMA and non-UMA modes. Advanced 2D-graphics system allows a variety of applications to deliver studio-quality text and graphics on television screens. Broadcom-developed device drivers enable rapid software development cycles with support of industry-standard operation systems. Industry-leading third party operating systems, toolchains and middleware supported. 65 nm process technology offers low power and lower cost.  图1。BCM7335单片系统方框图  图2。BCM7335参考设计框图 |
