SC-A142x

CRYSTAL CLOCK OSCILLATORS LVCMOS Data Sheet K2152 Rev. G SC-A1420 Series Description The SC-A1420 Series of quartz crystal oscillators 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. 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 3.3 Volt operation High shock resistance, to 1000g Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Ground Output VDD High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions Low Jitter - Wavecrest jitter characterization available No internal PLL avoids cascading PLL problems Metal lid electrically connected to ground to reduce EMI Gold plated pads 357 Beloit Street, P.O.
