pin connections for CSI-2 TX to external processor

Jump to solution

When using the CSI-2 TX with a Zynq Ultrascale+ and using pins selected within the IP block does there need to be anything between the FPGA and processor or is it a direct connection?

Hello @clutch12

Zynq Ultrascale + architecture have I/O that can natively support MIPI D-PHY. So for connecting MIPI compliant devices does not require any external hardware. You can directly connect from MIPI CSI-2 TX to MIPI compliant external devices.

For information on MIPI DPHY check PG202 (v4.1) (Page 8~9)

 @bpatil what if I have an Artix part? Can I just use a resistor network such as what Digilent has done on their zybo-z7 between the mipi/lp pins?

Hello @clutch12 

Yes, you can use resistor network or Meticom Solution for 7 series FPGA, For more details please check XAPP894
