ICS844021I-01 Datasheet (ICS) - CRYSTAL-TO- LVDS CLOCK GENERATOR

ICS844021I-01, CRYSTAL-TO- LVDS CLOCK GENERATOR

The ICS844021I-01 is an Ethernet Clock Generator and a member of the HiPerClocksTM HiPerClockS™ family of high performance devices from ICS.

The ICS844021I-01 uses an 18pF parallel resonant crystal over the range of 24.5MHz - 34MHz.

For Ether net applications, a 25MHz crystal is used.
