SC-1420 Series
Description
The SC-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-1420 units with a logic “1" or open enables its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load.
Features
Wide frequency range–1.0MHz to 80.0MHz 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 1000g Low Jitter No internal PLL avoids cascading PLL problems Metal lid electrically connects to ground to reduce EMI Gold plated pads
Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Ground Output VDD
