Recom m ended Transform ers:
BH Electronics 500-1776 (1:1.36);
Pulse Engineering PE 64937 (1:1.36); or
Pulse Engineering PE 65340 (1:1.36)Ê(for extended tem p range)
Alternatively, a dual part containing the 1:2CT & 1:1.36 transform ers
necessary for the receiver and the transmitter circuits can be used, i.e.:
BH Electronics 500-1777;
Pulse Engineering PE 64952; or
Pulse Engineering PE 65774Ê(for extended tem p range)
9.17 BackplaneTransmit Interface (BTIF)
The Backplane Transmit Interface allows data to be taken from a backplane in a
2048kbit/s serial stream and allows BPV transparency by accepting dual-rail
data.
9.18 Microprocessor Interface (MPIF)
The Microprocessor Interface allows the E1XC to be configured, controlled and
monitored via internal registers.
