BIOSTAR Z270GTN Mini-ITX Motherboard Review

Z270GTN Circuit Analysis Continued

BIOSTAR isn't using the ALC1220 we typically find on high-end motherboards but instead uses a Realtek ALC892. There is a sense amplifier as well as audio-grade capacitors used to improve audio.

Intel's i219v PHY is present, and together with the Gbit MAC in the PCH, provides 1Gbit LAN. A SuperLan surge protection SMD is used to protect the LAN port from static spikes. The main SuperIO on the motherboard is an ITE IT8613E.

An ELAN eKTF5832 microcontroller is used to provide RGB LED support for the heat sinks and two RED LED 5050 headers. An NXP level shifter converts digital video from the iGPU in the CPU into HDMI/DVI for the rear IO.
