Description
The ICS87951I is a low voltage, low skew 1-to-9 Differential-to-LVCMOS/LVTTL Clock Generator and a member of the HiPerClockS? family of High Performance Clock Solutions from IDT. The ICS87951I has two selectable clock inputs. The single ended clock input accepts LVCMOS or LVTTL input levels. The CLK1, nCLK1 pair can accept most standard differential input levels. With output frequencies up to 180MHz, the ICS87951I is targeted for high performance clock applications. Along with a fully integrated PLL, the ICS87951I contains frequency configurable outputs and an external feedback input for regenerating clocks with "zero delay".
