CRYSTAL CLOCK OSCILLATORS Data Sheet 0208F Rev. B LVDS with Tri-State SD-A2D00 Series PRELIMINARY Description The SD-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 range-50.0MHz 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 1000g * 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 Electrical Connection Pin Connection 1 N.C. 2 Enable/Disable 3 Ground 4 Output 5 Output Complement 6 VCC 357 Beloit Street, P.O.
