Feature Descriptions
Figure 1-7 shows the USB 2.0 ULPI transceiver circuitry. Note that the shield for the USB
Micro-B connector (J2) can be tied to GND by a jumper on header J51 pins 1–2 (default).
The USB shield can optionally be connected through a capacitor to GND by installing a
capacitor (body size 0402) at location C335 and jumping pins 2-3 on header J51.
SD Card Interface
[Figure 1-2, callout 5]
The ZC706 evaluation board includes a secure digital input/output (SDIO) interface to
provide user-logic access to general purpose nonvolatile SDIO memory cards and
peripherals. Information for the SD I/O card specification can be found at the SanDisk and
SD card websites [Ref 18], [Ref 19].
The SDIO signals are connected to XC7Z045 AP SoC PS bank 501 which has its VCCMIO set
to 1.8V. A MAX13035E high-speed logic-level translator (U11) is used between XC7Z045 AP
SoC 1.8V PS bank 501 and the 3.3V SD card connector (J30).
