Module ppm 

PPM / frequency conversion and crystal load capacitor calculator.

Sub-calculators:

1. XTAL load capacitor value: C_load = (C1×C2)/(C1+C2) + C_stray
2. Hz to PPM: PPM = (variation / center_freq) × 1,000,000
3. PPM to Hz: variation = center_freq × PPM / 1,000,000

Structs

HzToPpmResult

Result of a Hz→PPM conversion.

PpmToHzResult

Result of a PPM→Hz conversion.

XtalLoadResult

Result of a crystal load capacitor calculation.

Functions

hz_to_ppm

Convert frequency deviation to PPM.

ppm_to_hz

Convert PPM to frequency deviation.

xtal_load
