E 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 357 Beloit Street, P.
