| CRYSTAL CLOCK OSCILLATORS Positive ECL (PECL) Data Sheet 9727A Rev. N HA-A870 Series Description The HA-A870 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in industry standard four pin DIP hermetic package. Systems designers may now specify space-saving, costeffective packaged PECL oscillators to meet their timing requirements. Features * Wide frequency range-18.0MHz 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 * 3.3Volt operation * All metal, resistance weld, hermetically sealed package * Low Jitter Electrical Connection Pin 1 4 5 8 Connection Output Complement VEE /Ground Output VCC * MECL 10K and 10KH series compatible output on Pin 5, complement on Pin 1 * 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) Dimensions are in inches and (MM) 357 Beloit Street, P.O.
