SJ2820 Datasheet | NEL

Description The SJ-2820 Series of quartz crystal oscillators provide ECL 10K and 10KH series patible signals in a ceramic SMD package. Systems designers may now specify space-saving, cost-effective packaged ECL 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 ponent oscillators - High shock resistance, to 3000g - Metal lid electrically connected to ground to reduce EMI Electrical Connection Pin 1 2 3 4 Connection Output plement VCC /Ground Output VEE -4.5V - Low Jitter - ECL 10K and 10KH series patible output on Pin 3, plement 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 357 Beloit Street, P.O.
