Hi,
With reference to the RM46L830, we would like to know if there is any
details about the clock accuracy.
We understood that when using the cyrstal, the Main Oscillator circuit(OSCIN,OSCOUT)
will be connected to the external crystal with the necessary load capacitor.
And the output of the Main Oscillator will be the input to the PLL internally.
Please let me know if our below assumption is correct.
- The Main Oscillator's accuracy is exactly same as the external crystal?
As an example, if the external crystal circuit error is +10 ppm then Main Oscillator's
error is also +10 ppm?
Is there is any error induced by the internal oscillator itself?
- The accuracy of the Internal PLL is directly proportional to the accuracy of the
Main Oscillator which inturn is dependent on the external crystal?
Please let me know if there is any information on internal PLL's jitter.
Best Regards.
Prad
