Definition: A TCXO is a quartz crystal oscillator that includes temperature compensation circuitry to maintain stable frequency output over a wide temperature range.

Key Features:

• • High frequency stability (typically ±0.5 ppm to ±5 ppm)
• • Integrated temperature sensor and compensation network
• • Low power consumption
• • Compact size (commonly in SMD packages)

Applications:

• • GPS modules
• • Mobile communication devices (cellular base stations, radios)
• • IoT and wireless sensors
• • Test and measurement equipment

Advantages vs. Standard XO:

Note: TCXOs are preferred where precise timing is required under varying environmental conditions.
