Z390 Taichi Ultimate Circuit Analysis Continued
The audio solution consists of a Realtek ALC1220 rated up to 120dB with integrated amplifier going to the rear IO panel, an added NE5532 for front audio amplification, and Gold series audio capacitors.
We find an AQC107 from Aquantia, but we weren't able to get the heat sink off for a picture. The two other Gbit NICs are from Intel; an i219v and an i211AT.
The front USB 3.0 internal headers are from an ASMedia ASm1074 hub. The ASMedia ASM1562 is a re-driver for the USB 3.1 internal header, and we find an ASM1543 type-C switch on the back for that internal header.
For the extra SATA controller, WIFI card, and PCI-E x1 slots we find an ASM1184e PCI-E hub that will increase lane count for these low bandwidth devices. Since ASRock used that hub, they bypass Intel's CVNI ports in the PCH, so they used the non-CVNI version of the new Wireless AC 1.733Gbps cards, the 9260NGW. That also means in the future you can move this card into any WIFI M.2 slot and it will work, while on other boards that use CVNI ports, you will have to have CVNI (which is custom proprietary to Intel).
We find two Pericom PI3EQX dual port re-drivers for the four rear USB 3.1 ports. We also find a HyperBCLK chip on the motherboard; this chip is used to increase BCLK OC margins.
An ASMedia, ASM1061 is used to add two SATA6Gb/s ports. The main SuperIO is a Nuvoton NCT6791D, and a Nuvoton NCT5567D is used to expand fan control.
A Nuvoton N76E885AT is used to provide RGB LED control, and there is a Texas Instruments eFuse on board for the headers. We find many NXP quick switches used to switch around PCI-E and SATA bandwidth.
