GENERAL DESCRIPTION

The ICS85214 is a low skew, high performance 1-to-5 Differential-to-HSTL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLK0, nCLK0 pair can accept most standard differential input levels. The single ended CLK1 input accepts LVCMOS or LVTTL input levels. Guaranteed output and part to-part skew characteristics make the ICS85214 ideal for those clock distribution applications demanding well defined performance and repeatability.
