Overview
Orderable Part Numbers
The 92HDW74C2 is a high fidelity, 6-channel audio codec compatible with the Intel High Definition
(HD) Audio Interface. The 92HDW74C2 codec provides high quality, HD Audio capability to desktop
and multi-media notebook.
The 92HDW74C2 is designed to meet or exceed premium logo requirements for Microsoft’s Win-
dows Logo Program (WLP) 3.09 and revisions 4 as indicated in WLP 3.09.
The 92HDW74C2 provides stereo 24-bit, full duplex resolution supporting sample rates up to
192kHz by the DAC and ADC. 92HDW74C2 SPDIF outputs support sample rates of 192kHz,
176.4kHz, 96kHz, 88.2kHz, 48kHz, and 44.1kHz. 92HDW74C2 SPDIF input supports sample rates
of 96kHz, 88.2kHz, 48kHz, and 44.1kHz. Additional sample rates are supported by the driver soft-
ware.
The 92HDW74C2 supports a wide range of desktop and consumer 8 channel configurations.
MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the
92HDW74C2 has 8 General Purpose I/O (GPIO).
The port presence detect capabilities allow the codecs to detect when audio devices are connected
to the codec. Load impedance sensing helps identify attached peripherals for easy set-up and a bet-
ter user experience. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion
and removal for protection of notebook speakers.
The 92HDW74C2 operates with a 3.3V digital supply and either 3.3V, or 5V analog supply. It can
also work with 1.5V and 3.3V HDA signaling; the correct signalling level is selected dynamically
based on the power supply voltage on the DVDD-IO pin.
The 92HDW74C2 is available in a 48-pin LQFP Environmental (ROHS) package.
Add an “8” to the end for tape and reel delivery. Min/Mult order quantitiy 2ku.
