Octal E1 Line Interface Evaluation Board

Features

Description

The CS61880 evaluation board is used to demonstrate

the functions of a CS61880 Octal Line Interface Unit in

either E1 75 Ω or E1 120 Ω.

^zSocketed CS61880 Octal Line Interface Unit

^zBinding post connectors for power and line

interface connections

The evaluation board can be operated in either Hard-

ware mode or Host mode. In Hardware mode, switches

and bed stake headers are used to control the line con-

figuration and channel operations for all eight channels.

In Host mode (Serial or Parallel), the evaluation soft-

ware, switches, and bed stake headers are used to

control the line configuration and operating mode set-

tings for each channel.

^zComponents supplied for all operational

modes E1 75 Ω and E1 120 Ω

^zSocketed termination circuitry for easy

testing

^zConnector for IEEE 1149.1 JTAG Boundary

Scan

^zLED Indicators for Loss of Signal (LOS) and

power

^zSupports Hardware, Serial, and Parallel Host

Modes

^zEasy-to-use evaluation software

In both Hardware and Host modes, the board may be

configured for E1 75 Ω or E1 120 Ω operating modes. In

both modes binding post connectors provide easy con-

nections between the line interface connections of the

CS61880 and any E1 analyzing equipment, which may

be used to evaluate the CS61880 device. Bed stake

headers allow easy access to each channel’s clock and

data I/O digital interface.

^zOn-board socketed reference clock oscillator

Eight LED indictors display the Loss of Signal (LOS)

conditions for each channel during Hardware and Host

modes. An LED indictor is used on the Interrupt pin to in-

dicate a change of state.
