Differential Positive ECL (DPECL)
SK-B29B0 Series
Description
The SK-B29B0 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 - 350.0MHz to 1.7GHz
• User specified tolerance available
• Case at electrical ground
• Will withstand SMD reflow temperatures of 253°C
for 4 minutes maximum
• All metal, resistance weld, hermetically sealed
package
• High shock resistance, to 1500g
• Low Jitter - Wavecrest jitter characterization
available
• High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
• High Q Crystal actively tuned oscillator circuit
