V1.7 - 16th Sept 2020

3.4 Clocks

The ADM-XRC-9R1 provides a wide variety of clocking options. The board has a user-programmable clock

generator. These clocks can be combined with the FPGA's internal PLLs to suit a wide variety of communication

protocols.

An overview of the clock routing on the ADM-XRC-9R1 is given in

On-Board Digital System Clocks

. A description

of each clock follows.

Figure 4 : On-Board Digital System Clocks

3.4.1 300MHz Reference Clocks (REFCLK300M and FABRIC_CLK)

The fixed 300MHz reference clocks REFCLK300M and FABRIC_CLK are differential LVDS signals.

REFCLK300M is used as the input clock for both DDR4 SDRAM interfaces.

FABRIC_CLK is used as the reference clock for the IO delay control block (IDELAYCTRL).

3.4.2 PCIe Reference Clocks (PCIEREFCLK)

The 100MHz PCI Express reference clock is provided by the carrier card through the Primary XMC connector,

P5 at pins A19 and B19. This clock is buffered into two PCIe Express reference clocks that are forwarded to the

PS GTR and PL GTY transceivers.
