Si5364-EVB
EVALUATION BOARD FOR Si5364 SONET/SDH PRECISION
PORT CARD CLOCK IC
Description
Features
The Si5364-EVB is the evaluation board for the Si5364
SONET/SDH Precision Port Card Clock IC. This
evaluation board provides access to all signals
associated with normal operation of the device. This
circuit board also is designed to provide access to signals
that are reserved for factory testing purposes.
 Si5364 device can be powered directly from either a
3.3 or 2.5 V supply
 Differential I/Os ac-coupled on board
 Differential inputs terminated on board
 Control input signals are switch/jumper configurable
 Status outputs brought out to headers for access
 LED status indicators reflect state of status outputs
 LED status indicators can be disabled for device
power measurements
