I am using LMK04616 clock gen and am unable to produce a pulsed SYSREF. I can produce a continuous SYSREF but neither pulsed over SPI nor via the SYNC pin has worked so far. I have followed the guidance on the forum here: https://e2e.ti.com/support/clock-timing-group/clock-and-timing/f/clock-timing-forum/730208/lmk04616-sysref-spi-trigger-problem?tisearch=e2e-sitesearch&keymatch=LMK04616%2525252520sysref# but so far no luck. I can generate the rest of my clocks just fine. I have attached my initialisation data for producing 5 pulses over SPI on channels 0/1 and 4/5, I then write to reg 0x014 bit 5 to initiate the burst of pulses. When I read back these registers they are as I would expect. Can anyone advise?
