3.3.4. GT Clock Lines

GT clock lines are dedicated clock lines available only in Arria 10 GT devices.

Each ATX PLL has two dedicated GT clock lines that connect the PLL directly to the transceiver channels within a transceiver bank. The top ATX PLL drives channels 3 and 4, and the bottom ATX PLL drives channels 0 and 1. These connections bypass the rest of the clock network for higher performance. These channels can be used only for non-bonded configurations.
