4.6. MIPI D-PHY Placement Rules

Follow these placement rules when implementing your MIPI D-PHY design.

When implementing MIPI D-PHY design, you must follow the placement rules below. Some I/O pins cannot be implemented as single-ended pins.

Example: For a MIPI D-PHY design with 4 data lanes and 1 clock lane on byte location 1, the I/O pin with pin index 5,10, 23 and 26 cannot be implemented as single ended pins

For general purpose I/O placement guidelines, follow the I/O placement restrictions in the Agilex™ 5 General-Purpose I/O User Guide.
