VCXOs

Voltage Controlled Crystal Oscillators (VCXOs) are used mainly in the telecom, test and broadcast industry. They enable customers to adjust the frequency by as much as ±150ppm while the circuit is active and so match an incoming signal. IQD’s VCXO’s are available with a wide range of pullabilities and outputs; they are normally used in conjunction with a phase locked loop. We offer a wide capability and can consider custom designs for specific applications. Our range includes:
