16mb31-1 Mainboard STI5100 (IC101) 1. Introduction The STi5100 is a low-cost Omega2 (The STBus multipath unified interconnect provides high on- chip bandwidth and low latency accesses between modules. The interconnect operates hierarchically, with latency-critical modules placed at the top level. The multipath router allows simultaneous access paths between modules, and simultaneous read and write phases from different transactions to and from the modules.

SERVICE MANUAL The STi5100 has a local memory interface (LMI) and a flash and peripheral interface (FMI). The STi5100's local memory interface is used for all data requirements in unified memory applications, including graphics, video and audio buffers. It provides 16-bit wide DDR SDRAM support only at up to 166 MHz.

SERVICE MANUAL audio is downmixed before emerging as stereo or Dolby Pro Logic compatible encoded audio. Simultaneous MPEG audio decoding and output of Dolby streams on the S/PDIF is also supported. SRS Labs’ TruSurroundXT is also provided for two speaker virtual surround sound. The integrated DACs provide analog stereo output directly from the device using a single-ended interface.Multichannel streams can be passed through to the IEC958 output for external decoding.
