Z270X-GAMING SOC Circuit Analysis Continued

GIGABYTE is using the Realtek ALC1220 (integrated amplifier for the rear headphone jack) with an NE5532 amplifier in a DIP-8 socket along with a gain switch to reduce the gain from x6 to x2.5. Nichicon audio grade capacitors are used to improve audio, as is the physical audio signal division built into the PCB.

Intel's i219v PHY works with the Gbit MAC in the PCH to produce 1Gbit Intel LAN. ASMedia's new ASM2142 USB 3.1 controller along with a Texas Instruments type-C switch chip are used to produce the type-A and type-C USB 3.1 ports on the rear of the IO panel.

An IT7236AFN microcontroller is used for RGB LED control. An ASMedia ASM1061 produce two SATA6Gb/s ports from a single PCI-E lane.

The ITE IT8686E is the main SuperIO that provides PS/2, voltage monitoring, and other backbone system tasks. A smaller ITE IT8792E offers improved fan control and overclocking features. Two 128Mbit (16MB) BIOS ROMs provide dual BIOS functionality.

An ASMedia ASM1442K level-shifter shifts digital video into HDMI signaling for the rear IO's HDMI port. ASMedia ASM1480s switch around PCI-E bandwidth along with four NXP CBTL08GP053 quick switches. I am not sure why GIGABYTE didn't use more ASM1480s, but instead added in four NXP USB 3.1/DP/PCI-E 3.0 switches, perhaps to save space or because they are higher performing (10Gb/s instead of 8Gb/s).
