CRYSTAL CLOCK OSCILLATORS LVCMOS Data Sheet K2205 Rev. A SC-A1460 Series Description The SC-A1460 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-A1460 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-80.0MHz to 135.0MHz * 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 * High Reliability - NEL HALT/HASS qualified for crystal oscillator start-up conditions * High Q Crystal actively tuned oscillator circuit * 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 Electrical Connection Pin Connection 1 2 3 4 Enable/Disable Ground Output VDD 357 Beloit Street, P.O.
