SJ-A1450 Series
Description
The SJ-A1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS patible signals for bus connected systems. Supplying Pin 1 of the SJ-A1450 units with a logic “1" or open enables its pin 3 output. In the disabled mode, pin 3 presents a high impedance to the load. All units are designed to survive wave soldering operations without damage.
Features
- Wide frequency range- 4.0MHz to 40.0MHz
- 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
- Metal lid electrically connected to ground to reduce EMI Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Input Ground Output VDD
- 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
- TTL patible (HCT) at specified supply voltage
