CRYSTAL CLOCK OSCILLATORS
Rev. C
Differential Positive ECL (DPECL)
SK-2910 Series
Description
The SK-2910 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–122.0MHz to 300.0MHz
• User specified tolerance available
• Case at electrical ground
• Low Jitter
• Overtone technology
• High Q Crystal actively tuned oscillator circuit
• Will withstand vapor phase temperatures of 253°C • Power supply decoupling internal
for 4 minutes maximum
• All metal, resistance weld, hermetically sealed
package
• Dual ground plane for added stability
• No internal PLL avoids cascading PLL problems
• High frequencies due to proprietary design
• High shock resistance, to 1500g
