The power supply ripple test needs the corresponding judgment standarden-USTelligent Community 13Tue, 04 Aug 2020 13:46:51 GMThttps://devzone.nordicsemi.com/thread/263036?ContentTypeID=1Tue, 04 Aug 2020 13:46:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:afeb9492-b9be-4dc5-8164-173061c717b3Andreas<p>Hi,</p> <p>&nbsp;</p> <p>No, these are not in the datasheet.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/262889?ContentTypeID=1Tue, 04 Aug 2020 05:45:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9759660f-42d8-4bf1-8be0-43661fc22498liuxialsp<p><span>Are there any parameters in the datasheet?</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/262760?ContentTypeID=1Mon, 03 Aug 2020 11:12:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:362faaeb-4384-49ee-ae5f-c9df694ff202Andreas<p>Hi,</p> <p>&nbsp;</p> <p>Ripple on VDD should be &lt;100mVpp. DEC4 should not be a concern if the layout is done properly, but typically between 1.1V and 1.32V. Also DEC4 shall not be supplied externally or loaded.</p> <p>&nbsp;</p> <p>Best regards,<br />Andreas</p><div style="clear:both;"></div>
