Features, Applications

Description

The SC-A1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-A1440 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 to 180.0MHz User specified tolerance available Will withstand vapor phase temperatures of 253C for 4 minutes maximum Space-saving alternative to discrete component oscillators 3.3 Volt operation High shock resistance, to 1000g Low Jitter - Wavecrest jitter characterization available Electrical Connection Pin Connection Enable/Disable Ground Output VDD High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions High Q Crystal actively tuned oscillator circuit Power supply decoupling internal No internal PLL avoids cascading PLL problems High frequencies due to proprietary design Metal lid electrically connected to ground to reduce EMI Gold plated pads
