500 Series VCXO
Description
The 500 Series voltage controlled crystal oscillator
(VCXO) is designed to meet the requirements of phase
locked loops (PLL) for clock recovery and frequency
synthesis. Tuning ranges are available from ±25ppm to
±400ppm, with excellent tuning linearity. The 500
Series VCXO is available in a variety of packages
including 14-pin DIP, surface-mount and hermetically
sealed.
Frequency Range
• 64 KHz to 160 MHz
Applications
• Phase Locked Loops (PLL)
• Digital Telephony
• SARSAT Beacon
