TI-JESD204-IP: Please tell me how to customize the JESD204c IP core.

Part Number: TI-JESD204-IP

Tool/software:

Hello Experts.

I have a JESD204c IP core that supports an 8-lane, 1-channel ADC.
I am considering adapting it to support a 4-lane, 2-channel ADC.
Please tell me how I can customize it.
Alternatively, please tell me which documentation I should read.
The development tool is Vivado.
The FPGA being used is the UltraScale XCKU115-FLVB2104.

Best Regards.
