Hi,
As per below table Desired frequency is 460KHz and calculated frequency is 460.1226KHz
what will be the / How to calculate the tolerance of PWM Calculated frequency and what are the factors are affecting it (other than temperature).
| Desired Frequency | 460 | KHz | ||
| formulas | ||||
| PWM frequency = TBCLK /(TBPRD+1) | ||||
| TBCLK = VCLK3/(HSPCLKDIV*CLKDIV) | ||||
| Sec. PH clock | VCLK3 | 150 | MHz | |
| High speed clock div | HSPCLKDIV | 1 | ||
| Clock div | CLKDIV | 1 | ||
| timebase period | TBPRD | 325 | ||
| Time base clock | TBCLK | 150000000 | ||
| PWM Frequency | PWM fr | 460122.6994 | Hz | |
| 460.1226994 | khz | |||
| Result | TBPRD | PWM fr | ||
| 325 | 460.1226 | 0.1226 | + | |
