| CRYSTAL CLOCK OSCILLATORS CMOS Data Sheet 0634R Rev. - AC-A1460 Series Description The AC-A1460 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the AC-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 0.5MHz to 156.250MHz * User specified tolerance available * Space-saving alternative to discrete component oscillators * 3.3 Volt operation * High shock resistance, to 1000g * Low Jitter Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Ground Output VDD * High Q Crystal actively tuned oscillator circuit * No internal PLL avoids cascading PLL problems * High frequencies due to proprietary design * Metal lid electrically connects to ground to reduce EMI * Gold plated pads * RoHs Compliant, Lead Free Construction 357 Beloit Street, P.O.
