Chapter 1: KCU105 Evaluation Board Features
GTH Transceivers
[Figure 1-2, callout 13]
The KCU105 board provides access to 20 GTH transceivers:
Eight of the GTH transceivers are wired to the PCI Express x8 edge connector (P1)
Eight of the GTH transceivers are wired to the FMC HPC connector (J22)
One GTH transceiver is wired to the FMC LPC connector (J2)
One GTH transceiver is wired to SMA connectors (RX: J31, J30 TX: J29, J28)
Two GTH transceivers are wired to SFP/SFP+ Module connectors (P4, P5)
The GTH transceivers in the XCKU040 device 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 GTH Quad of interest. There are five GTH Quads on the KCU105 board with connectivity
as shown here:
Quad 224:
MGTREFCLK0 - not connected
MGTREFCLK1 - not connected
Contains 4 GTH transceivers allocated to PCIe lanes 4-7
Quad 225:
MGTREFCLK0 - PCIE_CLK_Q0_P/N PCIe edge connector clock
MGTREFCLK1 - not connected
Contains 4 GTH transceivers allocated to PCIe lanes 0-3
Quad 226:
MGTREFCLK0 - SMA_MGT_REFCLK_C_P/N SMA GTH clock input
MGTREFCLK1 - FMC_LPC_GBTCLK0_M2C_C_P/N
Contains one GTH transceiver allocated to FMC_LPC_DP0_C2M_P/N
Contains two GTH transceivers allocated to SFP_TX_P/N and RX_P/N SFP/SFP+
connectors SFP0 and SFP1
Contains one GTH transceiver allocated to SMA_MGT_TX_P/N and SMA_MGT_RX_P/N
SMA connector pairs
