Figure 90. Example of Calibrating Multiple I/O Banks with One Shared OCT Calibration BlockAs an example, this figure shows a group of I/O banks that has the same VCCIO voltage. The figure does not show transceiver calibration blocks.

Because banks 5A and 7A have the same VCCIO as bank 3A, you can calibrate all three I/O banks (3A, 5A, and 7A) with the OCT calibration block (CB3) located in bank 3A.

To enable this calibration, serially shift out the RS OCT calibration codes from the OCT calibration block in bank 3A to the I/O banks around the periphery.
