FEMTOCLOCKS CRYSTAL-TO-3.3V LVPECL FREQUENCY
SYNTHESIZER W/INTEGRATED FANOUT BUFFER
ICS843246
IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER
1
ICS843246AM REV A SEPTEMBER 21, 2006
PRELIMINARY
GENERAL DESCRIPTION
The ICS843246 is a Crystal-to-3.3V LVPECL Clock
Synthesizer/Fanout Buffer designed for Fibre
Channel and Gigabit Ethernet applications and is
a member of the HiperClockS family of High
Performance Clock Solutions from IDT. The output
frequency can be set using the frequency select pins and a
25MHz crystal for Ethernet frequencies, or a 26.5625MHz
crystal for a Fibre Channel. The low phase noise characteristics
of the ICS843246 make it an ideal clock for these demanding
applications.
