HS-A2870 Datasheet | NEL

Description The HS-A2870 Series of quartz crystal oscillators provide MECL 10K and 10KH series patible signals in industry standard four-pin DIP hermetic package. Systems designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing requirements. This device is intended to operate on positive voltage for PECL applications. 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 - 3.3 Volt operation - Metal lid electrically connected to ground to reduce EMI - Low Jitter Electrical Connection Pin 1 7 8 14 Connection Output plement VEE /Ground Output VCC - MECL 10K and 10KH series patible output on Pin 8, 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 - Ro HS pliant, Lead Free Construction (unless solder dipped leads are supplied) Dimensions are in inches and (MM) 357 Beloit Street, P.O.
