L64118

L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101) Preliminary Datasheet LSI Logic’s L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101) is a highly integrated set-top box control and communication device, combining most of the logic needed for a digital broadcast system (DBS) or cable set-top box onto a single chip. The L64118’s embedded 32-bit TinyRISC™ MIPS CPU core provides processing power to support transport and system data, as well as general-purpose system control. The L64118 interfaces directly to LSI Logic’s L64704 and L64724 (satellite), and the L64768 (cable) single-chip channel decoders, as well as to the L64105 MPEG-2 A/V decoder. The MPEG-2 transport and system demultiplexer can handle 32 Packet Identifications (PIDs) simultaneously, including audio, video, and generalpurpose data services. It integrates a Digital Video Broadcasting (DVB)compliant descrambler block, substantially increasing the security of the set-top box. The L64118’s synchronous External System Bus (EBus) communicates with external peripherals. The L64118 communicates with peripherals through serial, parallel, SmartCard, and infrared ports. Several generalpurpose I/O pins are provided that let system designers expand the system’s capabilities. The L64118 supports industry-standard SDRAM memory of up to 16 Mbytes, using 16 and 64 Mbit SDRAMs. The SDRAM interface supports PC66/100-compliant SDRAMS. The L64118 is offered in LSI Logic’s 3.3 V G10®-p cell-based techn...
