Hello, this is a custom FPGA Dev Board built around a SOM. Im concerned about crosstalk between the Video In signals at the bottom and the Video IN CLK since its also close to the 165 MHz digital signals.
Im most concerned about the SOM traces being differential pairs.
There are 2 HDMI outputs. The number of pins barely fits in 1 bank.
To avoid crosstalk on the SOM, I can route each signal only on the P traces (for example) and move HDMI2 (for example) to another bank. Presuming each pair on the SOM has adequate spacing this would solve my issue at the cost of now having many N single-ended traces scattered around, making them far away from the expansion/IO connector (expansion is just left over pins). This would also mean I have less expansion/GPIO diff pairs.
So I'm wondering if the crosstalk will be low enough so I wouldn't have to do this.
