... PECL INPUT OSCAR™ USER CONFIGURABLE CLOCK Description The ICS525-03 are the most flexible way to generate a high-quality, high-accuracy, high-frequency clock output from a PECL input. The name OSCaR stands for OSCillator Replacement, as they are designed to replace crystal oscillators in almost any electronic system. The user can configure the device to produce nearly any output frequency from any input frequency by grounding or floating the select pins ...

... I/O ports to switch frequencies. By choosing divides carefully, the number of inputs which need to be changed can be minimized. Observe the restrictions on allowed values of VDW and RDW. The output of the ICS525-03 can be determined by the following simple equation: Frequency = Input Frequency CLK ...
