ICS2309 3.3 VOLT ZERO DELAY / LOW SKEW BUFFER

The ICS2309 is a low phase noise, high-speed PLL based, low-skew zero delay buffer. Based on ICS’ proprietary low jitter Phase Locked Loop (PLL) techniques, the device provides eight low skew outputs at speeds up to 133 MHz at 3.3 V. The outputs can be generated from the PLL (for zero delay), or directly from the input (for testing), and can be set to tri-st.
