In the DS90UB954 there is a CSI TX frequency setting in register CSI_PLL_CTL (0x1F). This setting has 3 options for speed 400, 800, 1600 Mbps. Is there any other way to fine-grain control the TX frequency PLL?
We have an SoC that can handle up to 1200Mbps, but not 1600 Mbps. Right now, the fastest we can go is 800 Mbps. I would like to tune the transmitter somewhere between 800 and 1600 to increase our bandwidth. Is there any other settings or method to achieve a more fine-grained control over the CSI TX speed?
I have not tried it, but I found this similar question here: http://e2e.ti.com/support/interface/f/138/t/777100
Unfortunately, the "analog" registers are not documented in the datasheet.
Any ideas?
Thanks!
