84329-01
700MHZ, LOW JITTER, CRYSTAL-TO-3.3V
DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
GEneral Description
The 84329-01 is a general purpose, single output high
frequency synthesizer. The VCO operates at a frequency
range of 200MHz to 700MHz. The VCO frequency is
programmed in steps equal to the value of the crystal
frequency divided by 16. The VCO and output frequency
can be programmed using the serial or parallel interfaces to
the configuration logic. The output can be configured to divide
the VCO frequency by 1, 2, 4, and 8. Output frequency steps
as small as 125kHz to 1MHz can be achieved using a 16MHz
crystal depending on the output dividers.
