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.
ORDERING INFORMATION:
CDB61584A
The board may be configured for 100Ω twisted-pair T1,
75Ω 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.
