Product details
Overview
92HD73C1X5PRGXB2X8 from IDT (now part of Renesas) is a 6-channel HD Audio codec IC designed for Intel High Definition Audio interface compliance in notebook and desktop PC audio subsystems. It delivers stereo 24-bit resolution at up to 192 kHz sample rate, supports 5.1 surround audio, and integrates three headphone amplifiers, dual S/PDIF outputs, and digital microphone inputs for premium WLP 3/4-compliant systems.
For engineers reviewing the 92HD73C1X5PRGXB2X8 datasheet, 92HD73C1X5PRGXB2X8 pinout, 92HD73C1X5PRGXB2X8 application, or 92HD73C1X5PRGXB2X8 equivalent, key selection criteria include WLP 3/4 logo compliance, dual S/PDIF output capability, runtime-selectable 1.5V/3.3V HDA signaling, 9 analog ports with jack detection, and integrated analog mixer functionality.
Technical Context
The 92HD73C1X5PRGXB2X8 implements a full Intel HD Audio-compliant controller with AFG (Audio Function Group) architecture, supporting up to nine stereo analog ports (A–I), two independent S/PDIF transmitters, and configurable digital microphone interfaces (mono/stereo/quad). Its DSP-based audio processing enables system-level effects including Dolby Home Theater™ and Maxx Player™ via SKPI plug-ins.
Power management includes dynamic power state control per widget (P0–P3), EAPD (External Amplifier Power Down), pop/click mitigation, and flexible analog supply options (+3.3 V, +4 V, +4.75 V, +5 V). The codec supports low-voltage HDA signaling and features four adjustable VREF outputs for microphone biasing.
