[comp.arch] HSC

Hi,
Is anyone out there designing peripherals to talk to HSC?  HSC is
a proposed ANSI standard (X3T9.3).  For those that are unfamiliar:
HSC (High Speed Communications) is a point to point data channel that has
a 100Mbyte/S or 200Mbyte/S transfer rate depending on whether you use the 32
or 64 bit data width.  It uses one ecl 100 pin differential D-shell connector
per 32 bits of width.  HSC is unidirectional, and 2 channels must be used to
make a full duplex connection.  HSC is based on a 25MHZ (40ns) clock, and 
transfers one 64/32 bit word per clock once a connection is established.
HSC is for data only, and there is no address lines.  
Thanks,
Randy Scofield
