ICS8543 Description
The ICS8543 is a low skew, high performance 1-to-4 Differential-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage Differential Signaling (LVDS) the ICS8543 provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100Ω. The ICS8543 has two selectable clock inputs.
