ICS84330-02
700MHZ, LOW JITTER, CRYSTAL-TO-3.3V
DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84330-02 is a general purpose, single
ICS
output high frequency synthesizer and a
HiPerClockS™ _{member of the HiPerClockS™ family of High}
Perfor mance Clock Solutions from ICS. The
VCO operates at a frequency range of
250MHz to 700MHz. The VCO and output frequency can
be programmed using the serial or parallel inter-
faces to the configuration logic. The output can be config-
ured to divide the VCO frequency by 1, 2, 4, and 8. Output
frequency steps from 250kHz to 2MHz can be achiev-
ed using a 16MHz crystal depending on the output divid-
er setting.
