Figure 98. 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. This figure represents the top view of the silicon die that corresponds to a reverse view of the device package and illustrates the highest density device in the device family.

Because banks 3B, 4C, and 7B have the same VCCIO as bank 7A, you can calibrate all four I/O banks (3B, 4C, 7A, and 7B) with the OCT calibration block (CB7) located in bank 7A.

To enable this calibration, serially shift out the RS OCT calibration codes from the OCT calibration block in bank 7A to the I/O banks around the periphery.
