CMOS Compatible Enable/Disable
HA-A1370/A1380 Series
Description
The HA-A1370 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-A1370 units with a logic "0" enables the output on
Pin 5. Alternately, supplying pin 1 of the HA-A1380 units with a logic "1" enables its Pin 5 output. 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 20.0MHz
· 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
