SC-A1470

CRYSTAL CLOCK OSCILLATORS LVCMOS Data Sheet 0149A Rev. B SC-A1470 Series PRELIMINARY Description The SC-A1470 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-A1470 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 freqency range: 4.0MHz to 20.0MHz User specified tolerance ±100ppm 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 - Wavecrest jitter characterization available 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 power No internal PLL avoids cascading PLL problems Power Supply Decoupling Internal Metal lid electrically connected to ground to reduce EMI Gold plated pads 357 Beloit Street, P.O.
