X399 GAMING PRO CARBON AC Circuit Analysis Continued

The Realtek ALC1220 is used as the audio codec and offers 120dB output on an amplified rail. MSI adds in a Texas Instruments OP1652 operational amplifier for the front headphone outputs as well as Gold series Nippon-Chemicon audio capacitors and then divides the audio PCB from the rest of the motherboard to improve audio quality.

The Intel i211AT NIC is used for wired LAN while the Intel Wireless AC 8265 is used for wireless AC. The motherboard offers BIOS recovery through USB BIOS flashback (chip labeled 504N), and uses a 128Mbit ROM to store the actual ROM.

The two USB 3.1 ports on the rear IO are derived from the ASMedia ASM3142 USB 3.1 controller, and an ASMedia ASM1543 operates as the type-C port's switch and CC logic chip. The USB 3.1 type-C internal header gets another ASM1543, and also gets a Pericom PI3EQX USB 3.1 re-driver to re-drive the integrated USB 3.1 signal in the X399 Southbridge.

We find two ASmedia ASM1464 near the rear IO and two more near the internal USB 3.0 headers, and these are USB 3.0 re-drivers. They must be behind MSI's VR-Ready USB 3.0 ports, and they should ensure that data travels across longer USB 3.0 cables.

There are two clock generators on the motherboard, an ICS 9FGL121CAGLF, and an ICS BV0831AIL are used to help CPU base clock overclocking and I assume to allow for more than seven simultaneous devices to operate connected to the CPU. An ASMedia ASM1480 seems to be connected to the first clock generator and must switch between native signaling or between the two clock generators.

The Nuvoton NCT6795D is the main SuperIO controller and provides the PS/2 on the rear IO as well as system management. An NEC R5F104BEA programmable micro controller provides RGB LED, and digital RGB LED control.

You can also find two Nuvoton NCT5655Y GPIO chips that help to extend the SuperIO's fan control capabilities throughout the motherboard.
