ESCRIPTION
The ICS8432-11 is a general purpose, dual output
Crystal-to-3.3V Differential LVPECL High Frequency
HiPerClockS鈩?/div>
Synthesizer and a member of the HiPerClock鈩?/div>
S
family of High Performance Clock Solutions from
ICS. The ICS8432-11 has a selectable TEST_CLK
or crystal inputs. The TEST_CLK input accepts LVCMOS or
LVTTL input levels and translates them to 3.3V LVPECL
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 reference or crystal 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
ICS8432-11 makes it an ideal clock source for Fiber Channel
1 and 2, and Infiniband applications.
