X399 Professional Gaming Circuit Analysis Continued




The Realtek ALC1220 is rated for 120dB SNR for the main headphone output. The codec also has an integrated amplifier for the headphone/speaker jack, and ASRock added a Texas Instruments NE5532 to amplify the front panel header output. Gold electrolytic audio capacitors are used to improve audio quality, as is a physical PCB divide.





We find the Aquantia AQC107 NBase-T controller which supports 10Gbit, 5, 2.5, 1, and 100Mbit Ethernet. It is part of a new class of NICs and performs quite well. We find two Intel i211AT 1Gbit NICs on the motherboard as well.




An Intel Wireless AC 3168NGW 1x1 Wireless AC card is used to provide up to 433Mbps of WIFI. An ICS clock generator is used to enhance clock overclocking; its model number is ICS 9VRS4883BKLF.




Two Pericom PI3EQX USB 3.1 re-drivers improve USB 3.1 signals from the X399 chipset. An ASMedia ASM1543 type-C switch and CC logic chip are used for the rear IO panel's type-C port. A FlashBack IC provides the USB BIOS recovery feature.




The main SuperIO is a NuvoTon NCT6779D and provides system monitoring and PS/2 on the rear IO. A nuvoton N76E885AT20 provides RGB LED control, and a drivers and receivers chip (labeled 232GG) provides the COM port header.




The motherboard features two ASMedia ASM1480 that switch x4 PCI-E 3.0 from the CPU to either M2_1 or the U.2 port.
