Figure 1-5 shows the USB 2.0 ULPI Transceiver circuitry.
SD Card Interface
[Figure 1-2, callout 5]
The VC707 board includes a secure digital input/output (SDIO) interface to provide
user-logic access to general purpose nonvolatile SDIO memory cards and peripherals. The
SD card slot is designed to support 50 MHz high speed SD cards.
The SDIO signals are connected to I/O bank 13 which has its VCCO set to 1.8V. A TI
TXB0108 8-bit bidirectional voltage-level translator (U31) is used between the FPGA and
the SD card connector (U29). Figure 1-6 shows the connections of the SD card interface on
the VC707 board.
