GENERAL DESCRIPTION

The ICS853013 is a low skew, high performance dual 1-to-3 Differential-to-2.5V/3.3V/5V LVPECL/ECL Fanout Buffer and a member of the HiperclocksTM family of High Performance Clock Solutions from ICS. The ICS853013 operates with a positive or negative power supply at 2.5V, 3.3V, or 5V. Guaranteed output and part-to-part skew characteristics make the ICS853013 ideal for those clock distribution applications demanding well defined performance and repeatability.

FEATURES
