The GTY transceivers in the XCVU37P are grouped into four channels or quads. The XCVU37P has twelve GTY quads on the left side of the device and twelve GTY Quads on the right side of the device.

The VCU128 board provides access to 14 of the 24 GTY Quads:

  • Four of the GTY Quads are wired to QSFP[1:4] Module Connectors (J42, J39, J35, J32)
  • Six of the GTY Quads are wired to FMC+ HSPC connector DP[0:23] (J18)
  • Four of the GTY Quads are wired to the PCIe 16-lane edge connector (P1)
  • Ten GTY Quads are not used (GTYs 130, 133, 228-235)

The reference clock for a Quad can be sourced from the Quad above or the Quad below the GTY Quad of interest.
