+8GB eMMC
FLASH + 512Mb QSPI FLASH, and there are 2 crystal oscillators to
provide the clock, a single-ended 33.3333MHz crystal oscillator for the
PS system, and a differential 200MHz crystal oscillator for the PL logic
DDR reference clock.
PCIe x 8 Interface
It supports the PCI Express 3.0 standard, provides a standard PCIe x 8
high-speed data transmission interface, and the single-channel
communication rate can be as high as 8GBaud.
