Document Table of Contents Sharing an OCT Calibration Block on Multiple I/O Banks

An OCT calibration block has the same VCCIO as the I/O bank that contains the block. All I/O banks with the same VCCIO can share one OCT calibration block, even if that particular I/O bank has an OCT calibration block.

I/O banks that do not have calibration blocks share the calibration blocks in the I/O banks that have calibration blocks.

All I/O banks support OCT calibration with different VCCIO voltage standards, up to the number of available OCT calibration blocks.

You can configure the I/O banks to receive calibration codes from any OCT calibration block with the same VCCIO. If a group of I/O banks has the same VCCIO voltage, you can use one OCT calibration block to calibrate the group of I/O banks placed around the periphery.
