GENERAL DESCRIPTION

The ICS8725 is a high performance LVHSTL zero delay buffer and a member of the HiPerClockS? 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.
