| CRYSTAL CLOCK OSCILLATORS ECL Data Sheet 9327A Rev. R HS-2840 Series Description The HS-2840 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in industry standard five-pin DIP hermetic packages. Systems designers may now specify space-saving, costeffective packaged ECL oscillators to meet their timing requirements. Features * Wide frequency range-65.0MHz 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 * Metal lid electrically connected to ground to reduce EMI Electrical Connection Pin 1 7 8 9 14 Connection N.C. VEE Output /Output VCC Ground * Low Jitter * MECL 10K and 10KH series compatible output on Pin 8, complement on Pin 9 * 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 357 Beloit Street, P.O.

Footnotes: 1) Standard frequency stability (20,25,50ppm & others available) 2) VOL, VOH, referenced to ground (VCC) with VEE = -5.2V 3) Jitter performance is frequency dependent. Please contact factory for full characterization. 4) Tpd is phase shift between the falling edge of pin 8 at VCC-1.29V and rising edge of pin 9 at VCC-1.29V.
