The ZC706 Evaluation Board for the Zynq-7000 XC7Z045 All Programmable User Guide v1.0 (UG954), states that the SD Card level shifter (U11) is a TI TXB02612 SDIO port expander.
Is this correct?
No, this information is not accurate. The SD card level shifter (U11) used on the ZC706 is actually a Maxim MAX13035E voltage level shifter.
The Maxim device is correctly identified in the ZC706 schematic and ZC706 BOM.
UG954 (v1.1) correctly lists Maxim MAX13035E as the voltage level shifter on the ZC706.
