XRT5897ES

Rev. 1.00
Overview
This unit is a 7.0 by 7.0 inch circuit board that simplifies the evaluation of the XRT5897 seven
channel, 3.3 V, E1, line interface unit integrated circuit. Its features include use of a 4-layer
circuit board to minimize noise, provisions for an equipment-side loopback that simplifies
testing, and options for operation either with or without an external LOS (Loss of Signal) output
delay clock. Figures 1 and 2a through 2e and Table 2 show the demo board component layout,
circuit diagram, and parts list respectively.
Power Requirements
A well-regulated source of +3.3 Volts ± 5%V must be applied to the board at the red (positive)
and black (negative) banana jacks.
Equipment-side Digital Input and Output Connections
The component layout given in Figure 1 shows the location of the equipment-side digital
receiver input and transmitter output connections for each of the seven independent
transmitters and receivers. For versatility, the I/O connections on each channel may be made
to either a set of 6 test points, or to a 10-pin header that will accept a ribbon cable connector.
The tests points are convenient for lab evaluations and signal monitoring, while the ribbon cable
connections offer a method of integrating the XRT5897 board into a larger system.
Table 1 shows the I/O connections for Channel 1. It also applies to the other channels if the
digit indicating the Signal and Test Point name is changed to the appropriate channel (e.g. “1”
in RXPOS1, etc.). Note the pin 1 locations for the ribbon cable connectors that are shown on
the component layout. Pin 1 is at top left for Channels 1, 7 and 6, and at bottom right for
Channels 3, 2, 5 and 4. The schematic diagram given in Figure 2 may be used to verify these
connections.
