HA121A Overview
The HA-1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL patible 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.
HA121A Key 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 ponent oscillators
- High shock resistance, to 3000g
- All metal, resistance weld, hermetically sealed package
- Low Jitter
- High Q Crystal actively tuned oscillator circuit
- Power supply decoupling internal
- No internal PLL avoids cascading PLL problems
