A Temperature-Compensated Crystal Oscillator (TCXO) uses electronic circuitry to counteract the quartz crystal's temperature-frequency characteristics, achieving stability from 0.1 to 5 ppm. TCXOs are lower power and smaller than OCXOs (which use an oven for 0.01-50 ppb stability) but offer lower stability.
KCCS TCXO series includes: KT09 (10~100 MHz, ±0.5 ppm, SMD14×9) for low phase noise applications; KT05 (10~52 MHz, ±0.1 ppm, SMD7×5) for GNSS and LTE small cells; KT05 Ultra-Stable (±0.05 ppm) for high precision; KT05 G-Sensitivity (≤±0.3 ppb/g) for vibration environments; and KV25 (up to 500 MHz) for high frequency. Custom frequencies available.
