HS-A2920 Datasheet | NEL

Description The HS-A2920 Series of quartz crystal oscillators provide DPECL Fast Edge patible signals in industry standard four-pin DIP hermetic packages. Systems designers may now specify space-saving, costeffective packaged PECL oscillators to meet their timing requirements. Features - Wide frequency range- 50.0MHz to 155.520MHz - 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 - Fast rise and fall times <600 ps - Low Jitter - Overtone technology - 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) Electrical Connection Pin 1 7 8 14 Connection Output plement VEE /Ground Output VCC Dimensions are in inches and (MM) 357 Beloit Street, P.O.
