ESCRIPTION
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 ICS. The
ICS84021 has a selectable TEST_CLK or crys-
tal 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 can be programmed using
the serial or parallel interface to the configuration logic. The
low phase noise characteristics of the ICS84021 make it an
ideal clock source for Gigabit Ethernet, SONET, Fibre Chan-
nel 1 and 2, and Infiniband applications.
