https://devzone.nordicsemi.com/f/nordic-q-a/91910/digital-signal-input-5mhz-readingHello, I have a component (AMC1306) in which I input a signal of at least 5Mhz. When this signal is triggered to this component, it sends me back data at this same speed. This signal is a digital signal of &quot;1&quot; and &quot;0&quot; bits. So I have to get allen-USTelligent Community 13Thu, 15 Sep 2022 07:29:31 GMThttps://devzone.nordicsemi.com/thread/386293?ContentTypeID=1Thu, 15 Sep 2022 07:29:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a19ce3c-b052-42fb-ac8d-f35b2f2db1fdSimon Feutrier<p>Hi <a href="https://devzone.nordicsemi.com/members/dmitryz">Dmitry</a>&nbsp;,</p> <p></p> <p>Thank you for this great idea! It works perfectly. Plus SPIM use EasyDMA so that a good bonus.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/386063?ContentTypeID=1Tue, 13 Sep 2022 21:11:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a0552c0-1e93-4f53-9816-2d3b1032e9dfDmitry<p>Hi Simon,</p> <p>try to use SPIM running at 8 MHz for your case (CLKIN to SCK, DOUT to MISO). With active BLE link, an interrupt from SPIM may be blocked by SoftDevice ISR for up to 250 us, so ensure your buffers are long enough.</p><div style="clear:both;"></div>
