Fatal1ty X370 Gaming K4 Circuit Analysis Continued




ASRock is using the ALC1220, which has a single amplified output rated at 120dB SNR. To amplify the front panel header, ASRock uses the Texas Instruments NE5532 amplifier. Nichicon Gold series audio capacitors and a physical PCB divide improve audio quality.





ASRock uses Intel's i211AT for the wired NIC. A nuvoTon N76E885A is used as an RGB LED controller, and a Texas Instruments eFuse is used to ensure the motherboard is protected if you mess up the polarity when you plug in your RGB LED strip.




An ASMedia ASM1543 type-C switch and controller is found near the USB 3.1 type-C port on the rear IO panel. Two Pericom PI3EQX1002 USB 3.1 re-drivers are found below the USB 3.1 type-C and type-A ports on the rear IO, they improve the USB 3.1 signal from the X370 chipset.




Multiple ASMedia ASM1480 quick switches move around PCI-E bandwidth between slots and devices. NuvoTon's NCT6779D is the main SuperIO used on the motherboard to offer PS/2, monitor hardware, and control fans.




The Texas Instruments GD75232 driver and receiver chip is used for the COM port.
