Z170X-Ultra Gaming Circuit Analysis Continued




GIGABYTE is using the ALC892 audio codec instead of the common ALC1150, and there is no amplifier, but audio quality isn't too bad.





Intel is using the Intel Alpine Ridge USB 3.1/ThunderBolt 3 controller for the Type-C and Type-A port on the rear IO. The Texas Instruments TPS65982 is used for Type-C port switching and USB Power Delivery 2.0 control. One big feature of this motherboard is the 100W USB power support for the two ports controlled by the Alpine Ridge controller. The circuit uses a boost converter to output a maximum of 20V at 5A for 100W. The 100W cover is hiding a transformer or some type of choke, there are two 4C06 MOSFETs for switching the power, and the motherboard is protected by diodes to ensure the power doesn't flow back into the rest of the circuitry.




The Z170X-Ultra Gaming has tons of red LEDs all over the back and even front of the motherboard.




GIGABYTE made sure to use an Intel NIC for networking. The i219v is used as the PHY for the integrated MAC in the PCH. The motherboard has two 128Mbit BIOS ROMs for dual BIOS.




An iTE IT8628E is used as the main SuperIO that provides fan control, voltage/temperature monitoring, and provides PS/2 on the rear IO. The motherboard uses a level shifter to produce HDMI from the digital video output of the CPU.




There are four ASMedia ASM1480 PCI-E 3.0 quick switches located below the first PCI-E x16 slot to move x8 of CPU bandwidth between it and the x16 slot below it. There are other ASM1480s around the motherboard to switch PCH bandwidth.
