ICS8543
LOW SKEW, 1-TO-4 LVDS FANOUT BUFFER
FEATURES
4 LVDS outputs Designed to meet or exceed the requirements of ANSI TIA/EIA-644 Selectable differential HSTL or LVPECL clock inputs LVCMOS / LVTTL control inputs 3.3V operating supply 20 lead TSSOP 0°C to 70°C ambient operating temperature
GENERAL DESCRIPTION
The ICS8543 is a low skew, high performance 1-to-4 clock fanout buffer and a member of HiPerClockS™ 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.
,&6
Guaranteed output and part-to-part skew characteristics www.DataSheet4U.com make the ICS8543 ideal for those applications demanding well defined performance and repeatability.
