CRYSTAL CLOCK OSCILLATORS  
Rev. B  
Differential Positive ECL (DPECL)  
SN-A2970 Series  
PRELIMINARY  
Description  
The SN-A2970 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. This  
device is to operate using positive voltage and uses multiple ground pins for improved signal integrity. This  
device is intended to operate on positive voltage for PECL applications.  
Features  
• Wide frequency range–671.0MHz to 1.7GHz  
• User specified tolerance available  
• Case at electrical ground  
• High Reliability - NEL HALT/HASS qualified for  
crystal oscillator start-up conditions  
• Overtone technology  
• Will withstand vapor phase temperatures of 253°C • High Q Crystal actively tuned oscillator circuit  
for 4 minutes maximum  
• All metal, resistance weld, hermetically sealed  
package  
• High shock resistance, to 1500g  
• Low Jitter - Wavecrest jitter characterization  
available  
• Power supply decoupling internal  
• Dual ground plane for added stability  
• No internal PLL avoids cascading PLL problems  
• High frequencies due to proprietary design  
• RoHS Compliant, Lead Free Construction
