LVDS
SD-B2D00 Series
Description
The SD-B2D00 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–80.0MHz to 312.5MHz
• User specified tolerance available
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 1000g
• 2.5 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
• 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

Footnotes:
1) Standard frequency stability (±20,±25,±50ppm & others available)
2) With Load of 100 ohms across differential outputs.
3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20Mhz.
4) Tpd is phase shift between the falling edge of pin 4 and the rising edge of pin 5.
5) Open to enable pin also enables the output
