VCXO
A VCXO Voltage-Controlled Crystal Oscillator is a crystal oscillator that''s frequency can be adjusted by an externally applied voltage. VCXO''s have a wide variety of applications in frequency modulation (FM) and phase-locked-loop (PLL) systems. Typical deviation ranges can be 10 ppm to as much as 2000 ppm. The device that allows a crystal oscillator''s frequency to be voltage controlled is known as a varactor diode.

Disciplined OCXOS
GPS Disciplined OCXOs (Oven Controlled Crystal Oscillators) are a range of advanced clock modules which provide electrical timing functionality for distributed network systems. These units primarily revolve around the 1PPS (pulse per second) timing synchronisation signal produced by a GPS frequency receiver which is derived from transmitted timing information received from GPS satellite systems.

voltage controlled crystal oscillator
VCXO
A VCXO (Voltage Controlled Crystal Oscillator) is a crystal oscillator the output frequency of which is controlled by adding an external control voltage via a frequency control input on a variable capacitance component such as a varactor diode connected in parallel to a load capacitance (CL). Epson VCXOs are divided into two types according to Voltage-Frequency (V-F) characteristic slopes depending on the AFC (Automatic Frequency Control) input configuration of the VCXO. One is a VCXO with a positive V-F slope and the other is a VCXO with a negative V-F slope. Please note that the input voltage of a control circuit will vary according to the individual type, as shown in Figs. 3 and 4. Epson's VCXOs are capable of either, depending on the customer's preference. Epson's VCXOs have been increasingly used for broader applications such as slave oscillators in phased-lock loops, or frequency modulators. Among the above types, a VCXO combined with a TCXO is called a VC-TCXO , respectively. These components have the merit of delicately controlling their output frequency electrically.

Temperature Compensated Crystal Oscillators
TCXOS & VCTCXOS
Temperature Compensated Crystal Oscillators (TCXO) deliver excellent temperature characteristics combined with low power consumption and fast warmup. Voltage Controlled Temperature Compensated Crystal Oscillators (VCTCXO) combine the same excellent temperature characteristics, low power consumption and fast warmup with a voltage control function to allow precise tuning of the output frequency after PCB assembly and later, to compensate for any effects of aging as well as offering the ability to pull back to nominal frequency where there is a change of circuit conditions

Varactor tuned Gunn oscillators utilize high performance GaAs Gunn diodes and various cavity configurations to deliver moderate output power with low AM/FM noise and harmonic emissions. The oscillators are specially designed for a broader tuning bandwidth and an electrical tuning capability. The standard offering covers the frequency range of 8.2 to 110 GHz and features a self-locking set screw for fine frequency setting. While standard models offer a waveguide interface, a coaxial interface is also available. The performance of the oscillator can be further enhanced by adding an isolator, Gunn oscillator modulator/regulator, and temperature heater.
