ICS8432-111
700MHZ/350MHZ
DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS8432-111 is a general purpose, dual out-
put Differential-to-3.3V LVPECL High Frequency
Synthesizer and a member of the HiPerClockS
family of High Performance Clocks Solutions
from ICS. The ICS8432-111 has a selectable
differential CLK, nCLK pair or LVCMOS/LVTTL TEST_CLK.The
TEST_CLK input accepts LVCMOS or LVTTL input levels
and translates them to 3.3V LVPECL levels. The CLK, nCLK
pair can accept most standard differential input levels.The
VCO operates at a frequency range of 200MHz to 700MHz.
The VCO frequency is programmed in steps equal to the value
of the input differential or single ended reference frequency.
Output frequencies up to 700MHz for FOUT and 350MHz for
FOUT/2 can be programmed using the serial or parallel
interfaces to the configuration logic. The low phase noise
characteristics and the multiple frequency outputs of the
ICS8432-111 makes it an ideal clock source for Fibre Channel
1 and 2, and Infiniband applications.
