CMOS
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
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
