ICS840001-31 CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

ICS840001-31 CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

The ICS840001-31 is a two output LVCMOS/ LVTTL Synthesizer and a member of the HiPerClockS™ HiPerClocks TM family of high perfor mance devices from ICS. One output is the LVCMOS/ LVTTL main synthesized clock output (Q) and one output is a three-state LVCMOS/LVTTL reference clock (REF_CLK) output at .

Features
