4.1. Identifying Pin Assignments Based on Byte Location

In the MIPI D-PHY GUI, you must provide the pin placement location via the byte location. Look for the Byte Location parameter under the Link n Location for each Link n tab. Refer to the pin index table below for each MIPI configuration on the I/O bank. You can refer to the device pin-out files to identify the pin location with reference to the pin index. You can assign the pin location with the pin location identified.

Example for MIPI D-PHY design using 2 data lanes and 1 clock lane assigned to byte location 7: The pin index 84 and 85 are for data lane 0 (D0), pin index 86 and 87 are for data lane 1 (D1), and pin index 88 and 89 are for the clock lane (CLK).

Example for MIPI D-PHY design using 2 data lanes and 1 clock lane assigned to byte location 6: The pin index 72 and 73 are for data lane 0 (D0), pin index 74 and 75 are for data lane 1 (D1), and pin index 76 and 77 are for the clock lane (CLK).

Note:

* Based on the pin index, the even number is P pin and odd number is N pin for data lane or clock lane.

** These pins can be use as RZQ pin. Refer to Assigning RZQ Pin and Dedicated Reference Clock Pin for MIPI D-PHY IP for more details.
