Crosshair VII Hero Circuit Analysis Continued
The audio section uses the Realtek ALC1220, and it seems this is the one with improved microphone input SNR. We also find an ESS Sabre ES9023P DAC to improve audio quality, and a Texas Instruments RC4580I amplifier. We also get a physical PCB divide and Gold series Nichicon audio capacitors.
We find the tried and true Intel i211AT wired NIC on the motherboard. Wireless-AC is provided by a Realtek RTL8822BE WIFI card.
An ASMedia ASM3142 is used for rear USB 3.1, and an ASMedia ASM1543 type-C chip is used. A Pericom PI3EQX USB 3.1 Gen 2 re-driver improved the USB 3.1 signal for the type-C internal header.
We find an AURA chip for RGB LED control, as well as an ST Micro STM32F microcontroller used for addressable RGB, LED support. Two clock generators, an ICS 9DB633AGILF and ICS 9VRS4883BKLF, are switched by an ASM1480 depending on the operating mode of the system. It seems that this system allows you to change the CPU BCLK without changing the base clock used for generating DRAM/PCI-E/FCLK.
We find a 256Mbit BIOS ROM on the motherboard, which is twice the size we find on other X470 motherboards. ASUS says they are using only 16MB of the 32MB ROM, and that the extra space is to ensure future CPU support, in case AMD expands the BIOS size. A BIOS chip is used to facilitate USB BIOS recovery. The ITE IT8665E is used as the main SuperIO and handles monitoring and produces the PS/2 on the rear IO.
We find a ROG chip that seems to expand fan control and other ROG features and a TPU chip that should enhance monitoring and OC features.
We find multiple ASMedia ASM1480 PCI-E quick switches that move around PCI-E bandwidth. On the right, we find a differential operational amplifier, which is used to increase voltage monitoring accuracy.
