ICS84021
260MHZ, CRYSTAL-TO-LVCMOS / LVTTL
FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84021 is a general purpose, Crystal-to-
LVCMOS/LVTTL High Frequency Synthesizer
and a member of the HiPerClock S family of
High Performance Clock Solutions from ICS.
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 can be
programmed using the serial or parallel interface to the
configuration logic.
