DESCRIPTION

The evaluation board includes a socketed CS61584A

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. Bind-

ing posts and bantam jacks are provided for line

interface connections. Several BNC connectors provide

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

timing may be derived from a quartz crystal, crystal os-

cillator, or an external reference clock. Four LED

indicators monitor device alarm conditions.
