Z390 Phantom Gaming 7 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 Realtek's 2.5Gbit Gaming LAN controller on the back of the motherboard, RTL8125. The Intel i219V is the GBit Intel chip for the 1Gbit LAN port.
The rear USB 3.1 (10Gb/s, called USB 3.2 on rear IO panel) are re-driven by the Pericom PI3EQX, and the type-C port on the rear gets an ASMedia ASM1543 type-C switch chip. The internal USB 3.0 type-C header gets its own ASM1543 type-C switch chip.
An ASMedia ASM1074 is used as a USB 3.0 hub to produce two USB 3.0 internal headers. The ASMedia ASM1061 provides two SATA6Gb/s ports.
The Nuvoton NCT6791D is used as the SuperIO controller. The Nuvoton N76E885AT is the microcontroller used to control the RGB LEDs.
A Hyper BCLK chip is used to allow for better BCLK overclocking. The motherboard has two 128Mbit (16MB) BIOS ROM chips for redundancy.
