What is a Temperature Controlled Crystal Oscillator?
A temperature controlled crystal oscillator (TCXO) is a type of quartz crystal oscillator designed to maintain frequency stability despite temperature changes. It uses an additional circuit to compensate for frequency drift caused by temperature variations, providing higher accuracy compared to standard crystal oscillators.
Key benefits include:
- High frequency stability over a wide temperature range
- Compact design suitable for portable devices
- Lower power consumption compared to oven-controlled crystal oscillators (OCXOs)
- Reliable performance in extreme environmental conditions
These features make TCXOs indispensable in applications requiring precision and reliability.
