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

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.

Clock Oscillators
-
A crystal clock oscillator (sometimes referred to as a 'Standard Packaged Crystal Oscillator' or SPXO) is a 'plug and play' quartz crystal. It combines a quartz crystal resonator with an oscillator circuit in a single package to provide a fully functioning stand-alone oscillator circuit.

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.

Temperature compensated crystal oscillator
TCXO
-
A TCXO (Temperature compensated crystal oscillator) is a crystal oscillator with a temperature-sensitive reactance circuit in its oscillation loop to compensate the frequency-temperature characteristics inherent to the crystal unit. Epson's are classified into two types. One is a Direct-Type TCXOwith a temperature compensation circuit built into the oscillation loop. The other is an Indirect-Type TCXO with a temperature compensation circuit outside the oscillation loop, in which the oscillation frequency is therefore indirectly controlled.
