[comp.dcom.lans] Ethernet thinwire transceiver specs

andrew@megadata.mega.oz (Andrew McRae) (09/08/89)

Our design group is involved with some Ethernet interface work,
and a question has arisen concerning the specifications of
placing a BNC thinwire connector on a PCB and what restrictions
apply as to track length etc. I remember there was discussion some
months ago about ways and means of connecting thinwire, and the
length limitations between the transformer and the Tee connector.

Can someone mail me with the relevant specifications, or with
the experiences other designers have had in building this form of
thinwire tap interface. Can one, for example, have a low
capacitance cable (short!) between the PCB holding the transceiver,
and an offboard BNC connector mounted on a case?

Thanks mightily,
