X299-Aorus Gaming 9 Circuit Analysis Continued
The audio hardware on this motherboard consists of the Realtek ALC1220 codec along with a Texas Instruments NE5532 amplifier on the back of the PCB. Gold series capacitors were also used to improve audio quality as well as physical PCB division.
Woah! ASRock dropped that 1x1 433Mbps wireless-AC card and upgraded to the Intel 2x2 867Mbps 8265NGW. The first NIC is an i211AT.
The second NIC is an i219v PHY that works with the integrated MAC in the PCH. The ASMedia ASM3142 USB 3.1 controller is found on a daughterboard.
The ASMedia ASM1543 is used as the type-C switch and CC logic chip. The ASMedia ASM1074 USB 3.0 hub is used to expand USB 3.0 for the rear IO. The odd part is that ASRock could have routed all USB 3.0 to the PCH, as the PCH has many unused HSIO lanes. I believe that ASRock used the hub instead because it reduces the number of traces from the PCH. Mini-ITX boards such as this could use anywhere from 8-10 PCB layers, and reducing traces is the name of the game.
An ICS 6V41742B is used as an extra clock generator to improve BCLK clocking. The nuvoton NCT6791D is the main super IO used for fan control and major system monitoring, as well as the PS/2 port.
The Nuvoton N76E885AT is used for RGB LED control and functionality. The BIOS is a 128Mbit/16MB ROM. We also find an eFuse near the BIOS ROM.
