Title: Phantom clocks
Severe PCA9507 problem !!!! - #Phantom clocks
We have received a new batch of produced cards with PCA9507 assembled and observed that sometimes Phantom clocks are generated by the device on the A side (blue) (master connected on the B side(red) !
please see attached picture .
This did not happen in the previous batch of cards. No BOM changes were applied.
Did anyone ever encounter such a problem /
Any hints/directions to follow?
