Description
The HS-A1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HS-A1420 units with a logic “1" or open enables its
output. In the disabled mode, output pin 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– 40.1MHz to 70.0MHz
• 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
• 3.3 Volt operation
