Description
The ICS84021 is a general purpose, Crystal-to-LVCMOS/LVTTL High Frequency Synthesizer and a member of the HiPerClockS? family of High Performance Clock Solutions from IDT. The ICS84021 has a selectable TEST_CLK or crystal input. 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 of ICS84021 can be programmed using the serial or parallel interface to the configuration logic.
