Understanding Phase Noise in Low-Noise TCXO Design

What phase noise is

Phase noise describes random fluctuations of the signal phase, measured in dBc/Hz at offsets from the carrier; lower values mean a cleaner clock for RF systems.

Sources of noise

Crystal drive level, compensation circuitry, supply noise and the output buffer all contribute; low-noise TCXOs minimize each to keep the noise floor low.

Impact on systems

Higher phase noise degrades radar sensitivity, communication EVM and ADC sampling accuracy, making low-noise oscillators critical for these designs.

Power and Layout Practices for Cleaner TCXO Clock Signals

Clean power

Feed the TCXO from a dedicated low-noise LDO and decouple with a combination of 100 nF and 10 µF capacitors at the supply pin.

Ground integrity

Use a continuous ground plane under the TCXO and return output current directly under the trace to keep the signal path clean.

Avoid interference

Keep the clock trace away from switching regulators, high-speed buses and RF transmitters, and add a guard trace or shield where coupling is unavoidable.
