CROSSHAIR VIII HERO (WI-FI) Circuit Analysis Continued
Audio hardware includes a Realtek ALC1220 under an EMI shield, an ESS SABRE ES9023 DAC, a de-pop circuit, a bunch of high-end Nichicon audio capacitors, a physical PCB divide, and a Texas Instruments RC45801 amplifier.
Normal Gbit LAN comes from an i211AT Intel NIC, and 2.5Gbit LAN comes from an RTL8125. There is also a WIFI6 AX200 controller on the board.
The four rear USB 3.0 ports come from an ASMedia ASM1074 USB 3.0 hub. The internal USB 3.1 type-C header gets a PI3EQX USB 3.1 re-driver and an ASMedia ASM1543 type-C switch and CC logic chip.
All of the rear USB 3.1 ports utilize PI3EQX re-drivers, and while there is only one type-C port on the rear IO, we find two ASM1543 type-C switches, which is odd. ASUS is using a 256Mbit BIOS chip, which is a bit pricey but should offer support of more CPUs as time goes on, and we find a BIOS chip that facilitates flashback recovery of the UEFI ROM.
The Nuvoton NCT6798 is the SuperIO, and we find a TPU chip which should expand fan control and other ROG features.
There is an AURA RGB LED controller chip hidden under one of the PCI-E latches.
