Fatal1ty Z270 Gaming K6 Circuit Analysis Continued


Like other major motherboard vendors, ASRock has switched to the Realtek ALC1220 from the ALC1150 since it offers 120dB SNR and an integrated amplifier. To supplement the built-in amplifier, ASRock has added a Texas Instruments NE5532 to amplify the front panel output. Nichicon Gold series electrolytic audio capacitors, as well as a PCB divide, help improve audio playback quality.


ASRock is using two Intel NICs that support teaming. The i211AT is a standalone NIC from Intel, while the i219v is the PHY for the integrated MAC in the PCH. In the end, you have two Intel Gbit NICs on a sub $200 motherboard.


USB 3.1 is provided by an ASMedia ASM2142 which utilizes two PCI-E 3.0 lanes for bandwidth. The type-C port requires a type-C switch and CC logic chip, and for that ASRock is using the ASMedia ASM1543.


An ASMedia ASM1074 USB 3.0 hub is used to provide the two USB 3.0 internal headers from a single USB 3.0 port. An ASMedia ASM1061 provides two SATA6Gb/s ports.


A Realtek RTD2168 provides the VGA/D-SUB video output on the rear IO panel because the iGPU does not output analog video natively. An IDT6V41642B clock buffer is used to enhance BCLK margins for overclocking.


An ASMedia ASM1442K level shifter provides DVI/HDMI from the digital video output of the iGPU. The main SuperIO is a nuvoTon NCT6791D.


Multiple ASMedia ASM1480 quick switches are scattered around the motherboard and switch x2 PCI-E 3.0 each. A nuvoTon N76E88 is in charge of the RGB LED functionality, and a Texas Instruments TPS259261 eFuse ensures you don't short the motherboard if you mess up RGB LED strip wire polarity.
