CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL) Fast Edge
Data Sheet 9734D Rev. J
HS-2920 Series
Description
The HS-2920 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals in industry standard four-pin DIP hermetic packages. Systems designers may now specify space-saving, costeffective packaged PECL oscillators to meet their timing requirements.
Features
* Wide frequency range-50.0MHz to 200.000MHz * 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 * Metal lid electrically connected to ground to reduce EMI * Fast rise and fall times <600 ps * Low Jitter * 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 * RoHS Compliant, Lead Free Construction (unless solder dipped leads are supplied)

Footnotes: 1) Standard frequency stability (20,25,50ppm & others available) 2) VOL, VOH, referenced to ground (VEE) with VCC = 5.0V 3) Jitter performance is frequency dependent. Please contact factory for full characterization. RMS jitter bandwidth of 12kHz to 20MHz. 4) Tpd is phase shift between the falling edge of pin 8 at 2.0V and the rising edge of pin 1 at 2.01V.
