TCXO

A TCXO holds frequency accuracy as a board heats and cools, which most designs need long before an oven becomes justifiable. MV Electronics tests each temperature-compensated crystal oscillator against its stated grade before release, then ships nationwide. Temperature-compensated crystal oscillators offer a level of temperature stability that cannot be attained using XOs or VCXOs. By correcting for changes as a function of temperature, TCXOs provide excellent stability and low phase noise, enabling communications through cell phones, GPS, and wireless modules.

What Is a TCXO (Temperature Compensated Crystal Oscillator)?

Compensation circuitry measures the ambient temperature and applies a correcting voltage, which is how a TCXO keeps frequency inside a tight tolerance without an oven. Standard grades hold ±2.0 parts per million, and the tightest builds reach ±0.005. Power draw stays low and there is no warm-up delay, which suits battery equipment and fast startup. Short-term stability stays good enough for GPS receivers and base station equipment to hold lock. Handheld terminals, asset trackers, and bench instruments all depend on that correction. Cost and board area stay well below what an oven-based part demands.

Do We Stock the TCXO Your Design Needs?

Our catalog covers 5MHz to 600MHz across five stability grades, from standard through to the quantum TCXO. Output logic covers CMOS alongside clipped and full sine wave, across a 1.8V to 5.0V rail. Packages start at 2.0 x 1.6 mm and extend through low-profile discrete builds to DIP, on every temperature-compensated crystal oscillator. Low g-sensitivity versions hold 0.01 ppb per G for airborne and mobile equipment. Our crystal oscillators overview lists every technology we manufacture, which helps when a board mixes types. Requirements below the tightest compensated grade move to our OCXO range, where an oven takes over.

Who Should Supply Your TCXO?

TCXO buyers deal with the same engineers who set the compensation curve, which shortens every technical conversation. Compensation curves get tuned to the temperature band a product actually operates in, rather than a generic industrial range. A discontinued part number usually has a match inside our precision timing components catalog, found without redesigning the board. We quote and screen runs of a few dozen pieces exactly as a volume order gets handled. Spares, repairs, and reorders continue after production ends, which keeps a fielded system serviceable.

Choose Precision Solutions

‍ Grade selection comes down to the operating range, the power budget, and how much phase noise a receiver tolerates in a TCXO. Every temperature-compensated crystal oscillator ships with its measured stability and jitter data. Evaluation units go out ahead of qualification, and the results come back documented. We deliver to buyers and engineers throughout the United States. Whether the requirement is one prototype or a production release, contact us.
