CMOS
HA-A1440 Series
Description
The HA-A1440 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-A1440 units with a logic "1" or open enables its pin 5
output. In the disabled mode, pin 5 presents a high impedance to the load.
Features
Wide frequency range 70.1MHz to 125.0MHz
User specified tolerance available
Will withstand vapor phase temperatures of 253C
for 4 minutes maximum
Space-saving alternative to discrete component
oscillators
High shock resistance, to 1000g
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
upon request
RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
