Question asked by Williams.Gareth on Mar 18, 2017

I am beginning to experiment with this part but something has me a bit stumped.

The eval board says that the transmit filter is configured for a frequency of 150KHz with a sensitivity around 100KHz.

However the receive filter is resonant at 80Khz.


Is the eval expecting a master/slave arrangement with the master transmitting on 80Khz and slaves transmitting on 150Khz (or vice versa)?

I don't see how the st7580 can be configured for dual frequencies, and it's not what I wanted anyway.


Anyone have any explanation for this?


The eval docs don't describe what frequency configuration the st7580 should actually be configured for.
