Notes:
1. The figure shown is just one possible combination for the PCIe Gen1/Gen2 x4 mode.
2. The x6 and xN clock networks are used for channel bonding applications.
3. Each master CGB drives one set of x6 clock lines.
4. Gen1/Gen2 x4 modes use the ATX PLL or fPLL only.
6.
5. Use the pll_pcie_clk from either the ATX or fPLL. This is the hclk required by the PIPE interface.
In this case the Master PCS channel is logical channel 3 (physical channel 4).
