SJ-B2870
SJ-B2870 is CRYSTAL CLOCK OSCILLATORS manufactured by NEL.
Description
The SJ-B2870 Series of quartz crystal oscillators provide MECL 10K and 10KH series patible 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- 50.0MHz to 100.0MHz
- User specified tolerance available
- Will withstand SMD reflow temperatures of 253°C for 4 minutes maximum
- Space-saving alternative to discrete ponent oscillators
- High shock resistance, to 1000g
- 2.5 volt operation
- Metal lid electrically connected to ground to reduce EMI
- MECL 10K and 10KH series patible output on Pin 3, plement on Pin 1 Electrical Connection Pin 1 2 3 4 Connection Output plement VEE /Ground Output VCC
