IDT™ / ICS™ CLOCK SLICER USER CONFIGURABLE PECL OUTPUT ZDB 4
ICS527-03
CLOCK SLICER USER CONFIGURABLE PECL OUTPUT ZDB
Typical Example
Note: The series termination resistor is located before
the feedback
VDD
The following connection diagram shows the implementation of the example from the previous section.
This will generate a 50 MHz clock synchronously with a 40 MHz input. The layout diagram below will
produce the waveforms shown on the right.
