CMOS
HA-A1420 Series
Description
The HA-A1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-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 1.0MHz to 80.0MHz
· User specified tolerance available
· Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
· Space-saving alternative to discrete component
oscillators
· High shock resistance, to 3000g
· All metal, resistance weld, hermetically sealed
package
· 3.3 Volt operation
· 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
