This Python3 command line tool and library controls any of the Texas Instruments CDCE9xx family of programmable spread-spectrum clock generators on an I2C bus:
- CDCE913/CDCEL913: 1 PLL, 3 Outputs
- CDCE925/CDCEL925: 2 PLLs, 5 Outputs
- CDCE937/CDCEL937: 3 PLLs, 7 Outputs
- CDCE949/CDCEL949: 4 PLLs, 9 Outputs
- One class instatiates objects for entire family of devices
- Calculates PLL and PDIV configurations given input and desired output frequencies
- Excludes PLL configurations with VCO harmonics in sensitive bands (like GPS)
- Read and write individual registers by name
- Export and import configurations in JSON format
- Detects platform and uses appropriate I2C bus
Requires:
- Python >= 3.7
- smbus >= 1.1
- Adafruit-PlatformDetect >= 3.19.3
