STRIX Z270I Gaming Circuit Analysis Continued




ASUS is using the Realtek ALC1220, which offers 120dB SNR and an integrated headphone amplifier. To spice things up, ASUS also added two extra operational amplifiers, the Texas Instrument RC458, and OP1688. Nichicon Gold series audio capacitors and PCB isolation of the audio section help to improve overall audio quality.





Intel's i219v PHY compliments the integrated MAC in the PCH to produce the Intel NIC. ASUS's WIFI card is the Qualcomm QCNFA364A 2x2 Wireless AC/BT 4.1 controller.




The USB 3.1 internal header is controlled by the ASMedia ASM2142 and uses an ASMedia ASM1543 type-C controller. RGB LED control is derived from an AURA chip, and a Texas Instruments 2592AA eFuse helps protect the port from reversed polarity.




The nuvoTon NCT6793D SuperIO controls the fans and offers monitoring, while the TPU chip helps out with ASUS specific features such as automatic overclocking. A single 128Mbit (16MB) BIOS ROM holds the BIOS. The little chip labeled 6V4153 is a clock buffer, perhaps to enhance BCLK margins.
