700MHZ, CYRSTAL-TO-3.3V DIFFERENTIAL
LVPECL FREQUENCY SYNTHESIZER
ICS8432-51
IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER

ICS8432BY-51 REV. E APRIL 10, 2007
GENERAL DESCRIPTION
The ICS8432-51 is a general purpose, dual output
Cr ystal-to-3.3V Differential LVPECL High Fre-
quency Synthesizer and a member of the
HiPerClockS family of High Performance Clock
Solutions from IDT. The ICS8432-51 has a select-
able TEST_CLK or crystal input. The VCO operates at a fre-
quency range of 250MHz to 700MHz. The VCO frequency is
programmed in steps equal to the value of the input reference
or crystal frequency. The VCO and output frequency can be
programmed using the serial or parallel interface to the con-
figuration logic. The low phase noise characteristics of the
ICS8432-51 make it an ideal clock source for Gigabit Ethernet,
Fibre Channel 1 and 2, and Infiniband applications.
