Product details
Overview
92HD68E1X5NDGXZAX from Integrated Device Technology is a 10-channel HD Audio codec IC compliant with Intel's High Definition Audio Interface, delivering stereo 24-bit resolution at up to 192kHz sample rate. It integrates five stereo DACs and two stereo ADCs, supports full-duplex 7.1 audio plus simultaneous VoIP, and targets notebook and desktop PC audio subsystems requiring ECR15b/EuP low-power compliance.
For engineers reviewing the 92HD68E1X5NDGXZAX datasheet, 92HD68E1X5NDGXZAX pinout, 92HD68E1X5NDGXZAX application, or 92HD68E1X5NDGXZAX equivalent, key selection criteria include HD Audio interface compatibility, dual SPDIF I/O support, digital microphone input capability (mono/stereo/quad), integrated headphone amplifiers, and RoHS-compliant 40-pad QFN packaging.
Technical Context
The 92HD68E1X5NDGXZAX implements a fully programmable HDA widget-based architecture with eight analog ports (plus CD In), port presence detection, and configurable GPIOs supporting SPDIF/GPIO/digital microphone/VREF_OUT multiplexing. Its DSP engine enables system-level effects including 12-band parametric equalization, dynamics processing, and acoustic echo cancellation.
Power management includes AFG D0–D3 states with D3cold support, vendor-specific D4/D5 states, and low-voltage HDA signaling (1.5V/3.3V). The codec supports dynamic stream switching, analog/digital PC-beep routing to all outputs, and Microsoft WLP premium logo compliance via BIOS verb table configuration.
