MU9C8148
MU9C8148 is SRT Interface manufactured by Music.
DESCRIPTION
The MU9C8148 is a Source Routing Transparent (SRT) Interface for the MUSIC Semiconductors MU9C1480 LANCAM for use in Token Ring LAN Bridges and Brouters. This interface operates in accordance with IEEE standards while supporting address filtering rates up to 150,000 frames/sec for minimum-length frames. The MU9C8148 has four interfaces to provide glue-free address filtering. The Transceiver interface monitors receive data from the Transceiver to the MAC, and determines whether to filter according to Source Routing or Transparent Bridging standards. The MAC interface supplies Match, Fail, and Flush signals to instruct the Token Ring controller to reject or copy a frame. The LANCAM interface controls the panion LANCAM(s) for Transparent filtering. The Host Processor interface allows for direct initialization of the MU9C8148, and downloading of the filtering and purging routines, to offload the munication processor.
