Z270 Taichi Circuit Analysis Continued


We get a Realtek ALC1220 audio codec, which features an integrated headphone amplifier and 120dB SNR. A Texas Instruments NE5532 is used to amplify the front panel audio output, and then the PCB is physically isolated and gold series audio capacitors are put into use to help improve audio quality.


The Intel i219v is used as the PHY to complement the MAC integrated into the PCH. The Intel i211AT is used as the second standalone NIC.


The Intel WIFI controller is the Wireless AC 3168NGW rated for 1x1 433Mbps. An IDT 6V41642B acts as a clock buffer and improves BCLK overclocking margins.


The ASMedia ASM2142 provides USB 3.1 capabilities, and the ASMedia ASM1543 acts as the type-C switch and CC logic chip.


Two ASMedia ASM1061 provide four extra SATA6Gb/s ports.


An ASMedia ASM1074 acts as a USB 3.0 hub to expand one port into four for the internal USB 3.0 headers. The ASmedia ASm1184e expands a single PCI-E port into four and outputs to the two ASMedia SATA controllers, the WIFI card, and the x1 PCI-E slot as they don't really use much bandwidth.


The nuvoTon NXT6791D is used as the SuperIO, and the nuvoTon N76E885A is used as the RGB LED controller.


Two 128Mbit/16MB BIOS ROMs provide redundancy in case of BIOS corruption. There are also multiple NXP L04083B quick switches to move around PCI-E bandwidth for the GPU slots and between M.2 slots and the SATA ports.
