Description
The SK-A2910 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
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• Low jitter - Wavecrest jitter characterization avail-
able
• Wide frequency range—100.0 MHz to 320.0 MHz
• User specified tolerance available
• Case at electrical ground
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• All metal, resistance weld, hermetically sealed package
• High shock resistance, to 1500g
• Overtone technology
• High Q crystal actively tuned oscillator circuit
• 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
