Chapter 3: Board Component Descriptions
The XCVU9P-L2FSGD2104E FPGA (-2 speed grade) included with the VCU1525 board
supports up to Gen3 x16 and Gen4 x8.
The PCIe PEX_REFCLK_P/N pair is input from the CN1 edge connector and AC-coupled
directly to FPGA U1 Quad 226 MGTREFCLK0 pins AM11 (P) and AM10 (N) (also see
Figure 3-11).
28 Gb/s QSFP+ Module Connectors
[Figure 2-1, callout 13, 14]
The VCU1525 board hosts dual quad (4-channel) small form-factor pluggable (28 Gb/s
QSFP+) connectors (QSFP0 J7, QSFP1 J9) that accept 28 Gb/s and below QSFP+ optical
modules. Each connector is housed within a single 28 Gb/s QSFP+ cage assembly. QSFP0 J7
RX/TX lanes are wired to GTY bank/quad 231, and QSFP1 J9 RX/TX lanes are wired to GTY
bank/quad 230.
Figure 3-11 shows 28 Gb/s QSFP+ module connector circuitry typical to each connector.
The FPGA connections for each quad and for the QSFP control nets are listed in Appendix A,
Master Constraints File Listing.
