ATX Clock Divider
The ATX clock divider divides the ATX PLL high-speed clock and provides
high-speed serial and low-speed parallel clock for bonded functional modes such as
PCIe (×4 and ×8), Basic ×4 and ×8, and PMA-Direct mode with ×N configuration. For
PCIe functional mode support, the ATX clock divider consists of the PCIe rateswitch
circuit to enable dynamic rateswitch between PCIe Gen1 and Gen2 data rates. For
more information on this circuit, refer to
The clock outputs from the ATX PLL block are provided to the transmitter channels
through the ×N_Top or ×N_bottom clock lines, as shown in
