HA-121x Datasheet | NEL Frequency

Description The HA-1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL patible signals for bus connected systems. Supplying Pin 1 of the HA-1210 units with a logic “1" enables the output on Pin 5. In the disabled mode, Pin 5 presents a high impedance to the load. All units are resistance welded in an all metal package, offering RFI shielding, and are designed to survive standard wave soldering operations without damage. Insulated standoffs to enhance board cleaning are standard. Features - Wide frequency range- 0.5MHz to 36MHz - 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 - Low Jitter - High Q Crystal actively tuned oscillator circuit - Power supply decoupling internal - No internal PLL avoids cascading PLL problems - Low power consumption - Gold plated leads - Solder dipped leads available upon request - Ro HS pliant, Lead Free Construction (unless solder dipped leads are supplied) Electrical Connection Pin Connection 1 Enable Input 4 Grd & Case 5 Output 8 VCC .. et4u.Dimensions are in inches and (MM) .datashe 357 Beloit Street, P.O.
