LVDS with Tri-State
PJ-A2D00 Series
PRELIMINARY
Description
The PJ-A2D00 Series of quartz crystal oscillators provide LVDS compatible signals in a ceramic SMD
package. Systems designers may now specify space-saving, cost-effective packaged LVDS oscillators to
meet their timing requirements.
Features
Wide frequency range50.0MHz to 250.0MHz
User specified tolerance available
Will withstand vapor phase temperatures of 253C
for 4 minutes maximum
Space-saving alternative to discrete component
oscillators
High shock resistance, to 3000g
3.3 volt operation (other voltages available upon
request)
Metal lid electrically connected to ground to
reduce EMI
Enable/Disable (Tri-state)
LVDS output on pin 4, complement on Pin 5
Low Jitter - Wavecrest jitter characterization
available
High Reliability - NEL HALT/HASS qualified for
crystal oscillator start-up conditions
Overtone technology
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
