PRELIMINARY
FEMTOCLOCKS™ CRYSTAL-TO-LVDS FREQUENCY SYNTHESIZER
ICS844001-21
GENERAL DESCRIPTION
The ICS844001-21 is a a highly versatile, low IC S phase noise LVDS Synthesizer which can generate HiPerClockS™ low jitter reference clocks for a var iety of communications applications and is a member of the HiPerClocksTM family of high performance clock solutions from IDT. The dual crystal interface allows the synthesizer to support up to two communications standards in a given application (i.e. 1GB Ethernet with a 25MHz crystal and 1Gb Fibre Channel using a 25.5625MHz crystal). The rms phase jitter performance is typically less than 1ps, thus making the device acceptable for use in demanding applications such as OC48 SONET and 10Gb Ethernet.
