( Brand: Yaesu ), ( Model: TCXO-4 )
The TCXO-4, a Temperature Compensated Crystal Oscillator from Yaesu, is a high-performance, miniature oscillator designed for use in various applications, particularly in radio communication systems. This tiny yet powerful component measures only 2.5mm x 3.2mm x 1.0mm in size, making it an ideal choice for space-constrained devices.
The TCXO-4 boasts an exceptional temperature stability of 25ppb over the operating temperature range of -40 C to 85 C. This level of stability ensures that the output frequency remains consistently accurate, even under varying temperature conditions. The oscillator features a 10MHz output frequency, which can be easily divided or multiplied to meet specific application requirements.
The TCXO-4 is built using a high-quality quartz crystal, a low-noise temperature-controlled oscillator, and a precise temperature sensor. This combination results in an ultra-low phase noise of -145dBc/Hz at 1kHz offset, ensuring excellent signal quality and minimizing the impact of interference.
The oscillator is housed in a hermetically sealed, miniature ceramic package, offering superior protection against external factors such as moisture, dust, and vibrations. This robust construction ensures reliable operation even in harsh environments.
The TCXO-4 from Yaesu is an ideal choice for applications requiring high-stability and low-phase noise frequency sources, such as amateur radio transceivers, GPS receivers, and other communication devices. Its compact size, high performance, and excellent reliability make it a popular choice among engineers and hobbyists alike.

I calibrated the TCXO-4 to a tremble thunderbolt GPS ultra accurate reference MHz rated at parts per million it is original, fully functional and within specs. It can be installed in the following Yaesu radios: verify compatibility your radios manual ft-1000mp not mark-v ft-840 ft-600 frag-100 USA buyers only. It is plug and play no soldering. I removed this working unit from my Yaesu ft-1000mp because added a GPS reference instead.
