Fatal1ty B450 Gaming K4 Circuit Analysis Continued


Audio hardware includes a Realtek ALC892, some electrolytic audio capacitors, and the PCB is physically isolated to reduce noise.


The Gbit LAN comes from a Realtek RTL8111H controller. A Pericom PI3EQX re-drives both USB 3.1 signals for both ports on the rear IO panel, and an ASMedia ASM1543 is used as the type-C switch chip.


ASRock expands upon the number of default SATA6Gb/s ports with an ASmedia ASM1061. A Realtek RTD2168 is used to provide the D-SUB (VGA) port on the rear IO.


The motherboard's main SuperIO controller is the nuvoton NCT6779D. RGB LED control comes from a nuvoton N76E885AT controller.


The chip on the left labeled "232GG" is a drivers and receivers chip for the COM port. The motherboard utilizes a 128Mbit BIOS ROM.
