Description
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.
Features
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
