• One GTX transceiver is unused and is wired in a capacitively coupled TX-to-RX loopback
configuration
The GTX transceivers in Zynq-7000 series AP SoCs are grouped into four channels described
as Quads. The reference clock for a Quad can be sourced from the Quad above or Quad
below the GTX Quad of interest. There are four GTX Quads on the ZC706 board with
connectivity as shown here:
• Quad 109:
MGTREFCLK0 - FMC_HPC_GBTCLK0_M2C clock
°
MGTREFCLK1 - not connected
°
Contains 4 GTX transceivers allocated to FMC_HPC_DP[3:0]_C2M_P/N
°
• Quad 110:
MGTREFCLK0 - FMC_HPC_GBTCLK1_M2C clock
°
MGTREFCLK1 - SI5324_OUT_C_P/N jitter attenuator clock
°
Contains 4 GTX transceivers allocated to FMC_HPC_DP[7:4]_C2M_P/N
°
• Quad 111:
MGTREFCLK0 - FMC_LPC_GBTCLK0_M2C_C_P/N
°
MGTREFCLK1 - SMA_MGT_REFCLK_P/N SMA GTX clock input
°
Contains 1 GTX transceiver allocated to FMC_LPC_DP0_C2M_P/N
°
Contains 1 GTX transceiver allocated to SMA_MGT_TX_P/N and RX_P/N SMA
°
connectors
Contains 1 GTX transceiver allocated to SFP_TX and _RX_P/N SFP/SFP+ connector
°
Contains 1 GTX transceiver which is unused and is wired in TX-to-RX loopback
°
configuration
• Quad 112:
MGTREFCLK0 - PCIE_CLK_Q0_P/N PCIe edge connector clock
°
MGTREFCLK1 - not connected
°
Contains 4 GTX transceivers allocated to PCIe lanes 0-3
