Description The HS-870/880 Series of quartz crystal oscillators provide MECL 10K and 10KH series patible signals in industry standard four-pin DIP hermetic packages.. 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 ponent oscillators - High shock resistance, to 3000g - All metal, resistance weld, hermetically sealed package Electrical Connection HS-870 Pin Connection 1 7 8 14 N.C.
