SC-A1420-FREQ

The SC-A1420-FREQ is designed one kind of quartz crystal oscillators which provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying pin 1 of the SC-A1420 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.

It has eleven features. (1)Wide frequency range 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)3.3V operation. (6)High shock resistance to 1000g. (7)Low jitter, wavecrest jitter characterization available. (8)High reliability. (9)No internal PLL avoids cascading PLL problems. (10)Metal lid electrically connected to ground to reduce EMI. (11)Gold plated pads. Those are all the main features.

Some general characteristics have been concluded into several points as follow. (1)Its supply voltage would be min 3V and typ 3.3V and max 3.6V. (2)Its supply current would be min 0mA and max 40mA. (3)Its output current would be min 0V and max +/-16mA. (4)Its operating temperature range would be from 0°C to 70°C. (5)Its storage temperature range would be from -55°C to 125°C. (6)Its power dissipation would be max 144mW. (7)Its lead temperature would be 300°C. (8)Its load would be max 15pF. (9)Its start-up time would be max 10ms for 20MHz or greater and would be max 2ms for less tha  20MHz.

Also some electrical characteristics are concluded as follow. (1)Its frequency would be min 1MHz and max 80MHz. (2)Its duty cycle would be min 45/55% and max 55/45%. (3)Its logic 0 would be typ 0.1V and max 0.2V. (4)Its logic 1 would be min Vdd-0.2V and typ Vdd-0.1V. (5)Its rise&fall time would be max 8.0ns. And so on.
