CRYSTAL CLOCK OSCILLATORS
VCXO Series (PECL)
Data Sheet 0515F
Rev. F
SU-A369X Series
PATENT PENDING
Description
The
SU-A369X Series
of voltage controlled quartz crystal oscillators provide frequency control by applying
a voltage to Pin 1. This unit supplies DPECL compatible outputs which are enabled when Pin 2 is set to a
logic low or left open.
Features
• Frequency range–300.0MHz to 1.500GHz
• Wide Absolute Pull Range
• Will withstand SMD reflow temperatures of 183°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 1000g
• 3.3 volt operation
• Low Jitter - Wavecrest jitter characterization
available
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• High Q Crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• High frequencies due to proprietary design
• Gold plated pads

Footnotes:
1) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20MHz.
2) Frequency increase with increase in control voltage and is monotonic.
3) Pullability is frequency dependant. Consult factory.
4) Open to Enable pin also enables the outputs
