ADM-PCIE-8K5-FH User Manual

3.2 Clocking

The ADM-PCIE-8K5-FH provides reference clocks for the DDR4 SDRAM banks and the I/O interfaces available

to the user. After a clock is programmed to a certain frequency, that frequency will become the default on

power-up. Any clock out of an Si5338 Clock Synthesizer is re-configurable over I2C. This allows the user to

configure almost any arbitrary clock frequencies during application run time. Please see the Alpha Data API

functions for examples of how this is done.

Note: use "set_property BITSTREAM.CONFIG.UNUSEDPIN {Pullnone} [current_design]" to ensure the user

design does not interfere with the I2C interface to the reprogramable clock generator.

3.2.1 PCIe Reference Clocks

The 8 MGT lanes connected to the PCIe card edge use MGT tiles 224/225 and use the system 100 MHz clock

(PCIE_REFCLK).

A second PCIe reference clock is buffered up from the edge to the FireFly module MGT tiles (231/232).

3.2.2 Fabric Clock

The design offers a fabric clock called FABRIC_CLK which is permanently fixed at 200 MHz. This clock is

intended to be used for IDELAY elements in FPGA designs. The fabric clock is connected to a Global Clock (GC)

pin.
