TTL Compatible
Enable/Disable
HA-1210 Series
Description
The
HA-1210 Series
of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for
bus connected systems. Supplying Pin 1 of the HA-1210 units with a logic “1" enables the output on Pin 5.
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 36MHz
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
Low Jitter
High Q Crystal actively tuned oscillator circuit
