This happens because the input clock pin (CLK_IN) of the STV0299 is connected to the f_xtal/f_comp signal output pin (XT/COMP) of the TSA5059. After power-on reset the XT/COMP pin outputs f_xtal (test operation, see TSA5059 datasheet p. 10). The BSRU6 driver deactivates XT/COMP, the STV0299 gets no clock signal and the SU1278 freezes. > I can't test what happens if the bsru6 is used with the su1278 settings. I suppose the BSRU6 gets its clock signal directly from a crystal oscillator and the XT/COMP output pin is not used. It should also work with XT/COMP activated.
