Description
The ICS672-01 and ICS672-02 are zero delay buffers that generate four output clocks whose phases are spaced at 90° intervals. Based on ICS’ proprietary low jitter Phase Locked Loop (PLL) techniques, each device provides five low skew outputs, with clock rates up to 84 MHz for the ICS672-01 and up to 135 MHz for the ICS672-02. By providing outputs delayed one quarter clock cycle, the device is useful for systems requiring early or late clocks.
