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.
