•• All Required Components for CS61583

Evaluation

•• Locations to Evaluate Protection Circuitry

•• LED Status Indications for Alarm

Conditions

•• Control of Enhanced Hardware Options

General Description

The evaluation board includes a socketed CS61583

dual line interface device and all support components

necessary for evaluation. The board is powered by

an external +5 Volt supply.

The board may be configured for 100

Ω twisted-pair

T1, 75

Ω coax E1, or 120Ω twisted-pair E1 operation.

Binding posts and bantam jacks are provided for line

interface connections. Several BNC connectors pro-

vide clock and data I/O at the system interface.

Reference timing may be derived from a crystal oscil-

lator or an external reference clock. Four LED

indicators monitor device alarm conditions.
