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 120
Ω
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.
