Single-Chip Satellite Set-Top Dual TV Decoder with Integrated 8PSK
The BCM7328 is the second-generation of Broadcom's Dual Decode/Dual TV set-top box system on a chip. The BCM7328 integrates Broadcom's field-proven BCM4500 8PSK/TC Demodulator technology, as well as technology derived from Broadcom's cable products (such as the BCM7115 cable single-chip).
The BCM7328 memory subsystem is a unified memory architecture, (UMA), utilizing a 150-MHz Double Data Rate (DDR) memory interface that supports either 16-bit or 32-bit wide, depending on required system performance.
- Dual On-Chip 8PSK/ Turbo Code Demodulators 1-45 Mbaud variable rate receiver and DVB/DIRECTV®/Digicipher II Compliant FEC Decoder
- Support for DirecTV and MPEG Transport Streams
- Provides a cost-effective solution for Dual Decode, Direct Broadcast Satellite (DBS) applications
- Fully Integrated Dual 8PSK/ TC Receivers, MPEG2 A/V decoder, MIPS CPU and peripherals for complete Set-Top Box system
