SR-A2D20 Series
Data Sheet 0650B
Rev. E
Description
The SR-A2D20 Series of quartz crystal oscillators provide LVDS compatible signals in a ceramic SMD
package. Systems designers may now specify space-saving, cost-effective packaged LVDS oscillators to
meet their timing requirements.
Features
• Wide frequency range–100.0MHz to 640.0MHz
• User specified tolerance available
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 1000g
• 3.3 volt operation (other voltages available upon
request)
• Metal lid electrically connected to ground to
reduce EMI
• Enable/Disable
• LVDS output on pin 4, complement on Pin 5
• COTS/Dual use
Electrical Connection
Pin Connection
• Low Jitter - Wavecrest jitter characterization
available
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Overtone technology
• 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
• RoHS Compliant, Lead Free Construction

NEL recommends connecting the large
pad located between the general signal
pads to ground for heat transfer and
improved RF grounding.
