High Precision TCXO External Clock Module PPM0.1 for HackRF One SDR Radio Experiment - Temperature Compensated Crystal Oscillator with DIP Package

1. Application scenarios: WCDMA/LTE data analysis, etc.
2. The Hackrf One is used in scenarios with high clock requirements, such as GPS simulation, GSM/
3. Since the clock used by HACKRF is an inductive passive OC, the accuracy of the board is generally below 20PPM. The frequency ranges from 1 MHz to around 20 Hz, and from 1 GHz to around 20 KHz. Usually, the frequency changes with the environment. Generally speaking, this effect will not have any impact in scenarios with low requirements for wireless reception. After all, HACKRF has a 20 MHz bandwidth, but it has different meanings in wireless transmission. For example, in the GPS system, the frequency is 1575.42 MHz. When the PPM is 20, the frequency offset is 1575.42 MHz + (1575.42 * 20 = 0.0315084 MHz) = 1575.42 + 3, which cannot meet the application requirements of GPS. However, the accuracy of PPM 2 is certainly 0.003 MHz. It meets the requirements.

In addition, the external clock adopts a high-precision TCXO design, and the DIP packaging accuracy is 0.1 - 0.5 ppm.
