700MHZ, DIFFERENTIAL-TO-3.3V LVPECL
FREQUENCY SYNTHESIZER
ICS8432I-101
IDT / ICS 700MHZ, 3.3V LVPECL FREQUENCY SYNTHESIZER

ICS8432DYI-101 REV. C APRIL 10, 2007
GENERAL DESCRIPTION
The ICS8432I-101 is a general purpose, dual out-
put Differential-to-3.3V LVPECL high frequency
synthesizer and a member of the HiPerClockS
family of High Performance Clock Solutions from
IDT. The ICS8432I-101 has a selectable
TEST_CLK or CLK, nCLK inputs. The TEST_CLK input accepts
LVCMOS or LVTTL input levels and translates them to 3.3V
LVPECL levels. The CLK, nCLK pair can accept most standard
differential input levels. The VCO operates at a frequency
range of 250MHz to 700MHz. The VCO frequency is pro-
grammed in steps equal to the value of the input differential
or single ended reference frequency. The VCO and output
frequency can be programmed using the serial or parallel
interfaces to the configuration logic. The low phase noise
characteristics of the ICS8432I-101 makes it an ideal clock
source for Gigabit Ethernet and SONET applications.
