www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS Positive ECL (PECL) Data Sheet 0012C Rev. H SJ-A870 Series Description The SJ-A870 Series of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in a ceramic SMD package. Systems designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing requirements. Features • Wide frequency range - 15.0MHz to 250.0MHz • User specified tolerance available • Will withstand vapor phase tempera.

Systems designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing requirements. Features • Wide frequency range - 15.0MHz to 250.0MHz • User specified tolerance available • Will withstand vapor phase temperatures of 253°C for 4 minutes maximum • Space-saving alternative to discrete component oscillators • High shock resistance, to 3000g • 3.3 volt operation • Metal lid electrically connected to ground to reduce EMI • Low Jitter Electrical Connection Pin 1 2 3 4 Connection N.C. VEE /Ground Output VCC • MECL 10K and 10KH series compatible output on Pin 3 • 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) 357 Beloit Street, P.O.
