Gty Transceivers - Xilinx KCU116 User Manual

GTY Transceivers

[Figure 2-1, callouts 11, 12]
The KCU116 board provides access to 16 GTY transceivers:
• Eight of the GTY transceivers are wired to PCI Express
• Four of the GTY transceivers are wired to FMC HPC0 connector (J5)
• Four of the GTY transceivers are wired to zSFP/zSFP+ module connectors (J1, J3, J4, J6)
The GTY transceivers in the XCKU5P are grouped into four channels or quads. The reference
clock for a quad can be sourced from the quad above or the quad below the GTY quad of
interest. There are four GTY quads on the KCU116 board with connectivity as listed here (see
Figure 3-11):
Quad 224:
• MGTREFCLK0 - not connected
• MGTREFCLK1 - not connected
• Contains four GTY transceivers allocated to PCIe
Quad 225:
• MGTREFCLK0 - PCIE_CLK_Q0_P/N PCIe edge connector clock
• MGTREFCLK1 - not connected
• Contains four GTY transceivers allocated to PCIe lanes 0-3
Quad 226:
• MGTREFCLK0 - SFP_SI5328_OUT_C_P/N
• MGTREFCLK1 - USER_MGT_SI570_CLOCK_C_P/N
• Contains four GTY transceivers allocated to zSFP modules 0-3
Quad 227:
• MGTREFCLK0 - FMC_HPC0_GBTCLK0_M2C_C_P/N
• MGTREFCLK1 - FMC_HPC0_GBTCLK1_M2C_C_P/N
• Contains four GTY transceivers allocated to FMC_HPC0_DP[3:0]
