HiPerClockS鈩?/div>
HiPerClockS鈩?family of High Performance
Clocks Solutions from ICS. The VCO operates
at a frequency range of 250MHz to 500MHz.
Utilizing one of the outputs as feedback to the PLL output
frequencies up to 500MHz can be regenerated with zero
delay with respect to the input. Dual reference clock inputs
support redundant clock or multiple reference applications.
