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
