700MHZ, DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS8432-101 is a general purpose, dual out-
ICS
put Differential-to-3.3V LVPECL high frequency
HiPerClockS™ synthesizer and a member of the HiPerClockS™
family of High Performance Clock Solutions from
ICS. The ICS8432-101 has a selectable TEST_CLK
or CLK, nCLK inputs. The TEST_CLK input accepts LVCMOS
or LVTTL input levels and translates them to 3.3V LVPECL lev-
els. The CLK, nCLK pair can accept most standard differen-
tial input levels. The VCO operates at a frequency range of
250MHz to 700MHz. The VCO frequency is programmed in
steps equal to the value of the input differential or single ended
reference frequency.
