Differential Positive ECL (DPECL)
SJ-B2870 Series
Description
The
SJ-B2870 Series
of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals
in a ceramic SMD package. Systems designers may now specify space-saving, cost-effective packaged
PECL oscillators to meet their timing requirements.
Features
Wide frequency range–50.0MHz to 100.0MHz
User specified tolerance available
Will withstand SMD reflow temperatures of 253°C
for 4 minutes maximum
Space-saving alternative to discrete component
oscillators
High shock resistance, to 1000g
2.5 volt operation
Metal lid electrically connected to ground to
reduce EMI
MECL 10K and 10KH series compatible output on
Pin 3, complement on Pin 1
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
Power supply decoupling internal
No internal PLL avoids cascading PLL problems
High frequencies due to proprietary design
Gold plated leads - Solder dipped leads available
upon request
RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
