GENERAL DESCRIPTION

The ICS8543 is a low skew, high performance 1-to-4 clock fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. 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 accepts any differential input level and translates it to 3.3V LVDS output levels.
