Maximum crystal series resistance of LPC4300

[yoshiyukiokada]

I found something doesn't feel right with table data in LPC4300 datasheet.

In the table 41, "Recommended values for CX1/X2 in oscillation mode", there are two figures and they are same value " < 160ohm" on the line where Fundamental osccillation freq is 12MHz.

What is the difference between these two?

Hi, 

Yes, I think it is a mistake, but at the end, you know that we need to keep the Cext and Z of the Oscillator in the same value in order to get the resonance of the crystal oscillator.
