ICS840021I Datasheet (Integrated Circuit Systems) - CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

ICS840021I, CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

The ICS840021I is a Gigabit Ethernet Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS.

The ICS840021I uses a 25MHz crystal to synthesize 125MHz.

The ICS840021I has excellent phase jitter performance, over the 1.875MHz * 20MHz integrat
