ICS84329-01
700MHZ, LOW JITTER, CRYSTAL-TO-3.3V
DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS84329-01 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 thecrystal 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.
FEATURES
• Fully integrated PLL, no external loop filter requirements
• 1 differential 3.3V LVPECL output
• Crystal oscillator interface
• Output frequency range: 25MHz to 700MHz
• VCO range: 200MHz to 700MHz
• Parallel interface for programming counter
and output dividers during power-up
• Serial 3 wire interface
• RMS Period jitter: 5.5ps (maximum)
• Cycle-to-cycle jitter: 35ps (maximum)
• 3.3V supply voltage
• 0°C to 70°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free
(RoHS 6) packages
