ICS8432-51
700MHZ, CRYSTAL-TO-3.3V DIFFERENTIAL
LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS8432-51 is a general purpose, dual output
Crystal-to-3.3V Differential LVPECL High Frequency
Synthesizer and a member of the HiPerClockS
family of High Performance Clocks Solutions from
ICS. The ICS8432-51 has a selectable TEST_CLK
or crystal inputs. The TEST_CLK input accepts LVCMOS or
LVTTL input levels and translates them to 3.3V LVPECL levels.
The VCO operates at a frequency range of 200MHz 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 interfaces to the configuration logic.
The low phase noise characteristics of the ICS8432-51 makes
it an ideal clock source for Gigabit Ethernet, Fiber Channel 1 and
2, and Infiniband applications.
