Table 1: Equipment-side Signal Connections
Note:
Installing the two jumpers next to a ribbon cable connector implements an
equipment-side loopback on that channel.
Transmitter Line Output and Receiver Line Input Connections
Three-circuit one quarter inch audio-type jacks are used for the transmitter line-side output and
receiver line-side input of each channel. These jacks accept the patch cord plugs that are
commonly used for interconnecting 120 Ohm balanced lines that are used with E1 test
equipment.
Loopback Provisions
A signal source capable of transmitting and receiving dual-rail data having TTL or 3.3 V CMOS
compatible levels is necessary in order to test the XRT5894 receivers and transmitters
individually. Commercially-available E1 test sets normally do not operate with these signals.
However, an equipment-side loopback permits operation of the demo board with readily
available test equipment. This loopback may be implemented on any channel by installing the
two jumper shunts located next to the 10-pin ribbon cable connector for that channel. If these
shunts are installed on Channel 1, the receiver outputs RXPOS1 and RXNEG1 are connected
to the transmitter inputs TXPOS1 and TXNEG1 respectively. Now, Channel 1 may be tested
by connecting the output of an E1 pattern generator to the Channel 1 receiver input, RX1, and
the 120 Ohm input of an error detector to the Channel 1 transmitter output, TX1.
