ICS84321
260MHZ, CRYSTAL-TO-3.3V DIFFERENTIAL
LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84321 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 Clock Solutions from
ICS.The ICS84321 has a selectable TEST_CLK or
crystal inputs.The VCO operates at a frequency range of 620MHz
to 780MHz. 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.
