HA-1520 Series
Description
The HA-1520 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for
bus connected systems. Supplying Pin 1 of the HA-1520 units with a logic “1" enables its 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 85.0MHz
• User specified tolerance available
• Low Jitter
• High Q Crystal actively tuned oscillator circuit
• Will withstand vapor phase temperatures of 253°C • Power supply decoupling internal
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• No internal PLL avoids cascading PLL problems
• Low power consumption
• Gold plated leads - Solder dipped leads available
upon request
• High shock resistance, to 3000g
• All metal, resistance weld, hermetically sealed
