Description

The HS-1520 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for

bus connected systems. Supplying Pin 1 of the HS-1520 units with a logic “1" enables its output on Pin 8.

In the disabled mode, Pin 8 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 85.0MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C

• Space-saving alternative to discrete component

• High shock resistance, to 3000g

• All metal, resistance weld, hermetically sealed
