ESCRIPTION
The ICS8430BI-71 is a general purpose, dual out-
put Crystal/LVCMOS-to-3.3V Differential LVPECL
High Frequency Synthesizer and a member of the
HiPerClockS family of High Performance Clock
Solutions from ICS. The ICS8430BI-71 has a se-
lectable crystal oscillator interface or LVCMOS TEST_CLK.
The VCO operates at a frequency range of 250MHz to
700MHz. With the output configured to divide the VCO
frequency by 2, output frequency steps as small as 2MHz
can be achieved using a 16MHz crystal or test clock. Output
frequencies up to 700MHz can be programmed using the
serial or parallel interfaces to the configuration logic. The low
jitter and frequency range of the ICS8430BI-71 make it an
ideal clock generator for most clock tree applications.
