www.DataSheet4U.com CRYSTAL CLOCK OSCILLATORS Differential Positive ECL (DPECL) Data Sheet 9938B Rev. L SJ-2870 Series Description The SJ-2870 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–18.0MHz 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 Metal lid electrically connected to ground to reduce EMI Low Jitter Electrical Connection Pin 1 2 3 4 Connection Output Complement VEE /Ground Output VCC MECL 10K and 10KH series compatible output on Pin 3, 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) 357 Beloit Street, P.O.
