SC1420

The SC1420 series are designed as quartz crystal oscillators which provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supply 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.

SC1420 has nine features. (1)Wide frequency range which would be from 1MHz to 80MHz. (2)User specified tolerance available. (3)Will withstand vapor phase temperatures of 253°C for 4 minutes maximum. (4)Space saving alternative to discrete component oscillators. (5)High shock resistance to 1000g. (6)Low jitter. (7)No internal OLL avoids cascading PLL problems. (8)Metal lid electrically connects to ground to reduce EMI. (9)Gold plated pads. Those are all the main features.

Some general characteristics of SC1420 are concluded into several points as follow. (1)Its supply voltage would be min 4.75V and typ 5.0V and max 5.25V. (2)Its supply current would be min 0mA and max 40mA. (3)Its output current would be min 0mA and max +/-16mA. (4)Its operating temperature range would be from 0°C to 70°C. (5)Its storage temperature temperature range would be from -55°C to 125°C. (6)Its power dissipation would be max 210mW. (7)Its lead temperature would be max 300°C soldering 10 seconds. (8)Its load would be max 15pf. (9)Its start-up time would be max 10ms with conditions of 20MHz or greater and would be max 2ms with conditions of less than 20MHz.

Also some electrical characteristics of SC1420 are concluded as follow. (1)Its frequency would be min 1.0MHz and max 80MHz. (2)Its duty cycle would be min 45/55% and max 55/45%. (3)Its output voltage logic 0 would be max 0.2V. (4)Its logic 1 output voltage would be min Vdd-0.2V, (5)Its rise&fall time would be max 8ns. And so on.
