com CDB61584A Product Databook FEATURES s Socketed CS61584A Dual Line Interface s All Required Components for CS61584A Evaluation s Locations to Evaluate Protection Circuitry s LED Status Indications for Alarm Conditions s Support for Hardware and Host Modes Dual Line Interface Unit 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 100Ω twisted-pair T1, 75Ω coax E1, or 120Ω twisted-pair E1 operation.
Binding 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 oscillator, or an external reference clock.
Four LED indicators monitor device alarm conditions.

Zener diode Z1 protects the components on the board from reversed supply connections and over-voltage damage.
Capacitor C16 provides power supply decoupling and ferrite bead L1 helps isolate the CS61584A and buffer supplies.
Both sides of the evaluation board contain extensive areas of ground plane to insure optimum performance.
Capacitors C3, C5-C8, C13, C18, and C38 pro...
