ICS8432-101
700MHZ,
DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS8432-101 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
ICS. The ICS8432-101 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 programmed in steps equal to the value of the input differ-
ential 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 ICS8432-101 makes it an ideal
clock source for Gigabit Ethernet and SONET applications.
