GENERAL DESCRIPTION

The ICS8547 is a Hex low skew, high performance 1-to-2 Differential-to-LVDS Clock Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. Utilizing Low Voltage Differential Signaling (LVDS) the ICS8547 provides a low power, low noise, point-to-point solution for distributing clock signals over controlled impedances of 100Ω. The ICS8547 has six selectable clock inputs. The CLKx, nCLKx pairs can accept any differential input levels and translates them to 3.3V LVDS output levels.

FEATURES
