CSI-2 transmitter

Does anyone have a project with a CSI-2 transmitter?

For example, on 10M50 eval board.

Because no matter how hard we try, mistakes always occur:

Error: Pin "TX_HS_CP" requires a pseudo-differential I/O assignment.

or

Error: Can't place node "TX_HS_CP" -- node is a differential I/O node

or

Error: Can't place differential I/O pins and/or associated SERDES transmitters or receivers -- location assignments are illegal

Error: Pin "TX_HS_CP" with Differential 1.8-V HSTL Class I I/O standard must be driven by the external clock output of an enhanced PLL
