| CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 9942B Rev. K SJ-A370 Series Description The SJ-A370 Series of quartz crystal oscillators are designed to survive standard wave soldering operations without damage. Features * Wide frequency range-2.25MHz to 70.0MHz * 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 * Low Jitter * Low power consumption Electrical Connection Pin 1 2 3 4 Connection N.C. Ground Output VDD * TTL compatible (HCT) at specified supply voltage * High Q Crystal actively tuned oscillator circuit * Power supply decoupling internal * No internal PLL avoids cascading PLL problems * High frequencies due to proprietary design * Metal lid electrically connected to ground to reduce EMI * Gold plated leads * RoHS Compliant, Lead Free Construction 357 Beloit Street, P.O.
