1. DESCRIPTION
92HD71B5
4-CHANNEL HD AUDIO CODECS OPTIMIZED FOR LOW POWER
1.1.
Overview
The 92HD71B is a family of high fidelity, 4-channel audio codecs compatible with the Intel High Defi-
nition (HD) Audio Interface. The 92HD71B codecs provide high quality, HD Audio capability to note-
book and cost sensitive desktop PC applications.
92HD71B variants:
The higher performance and quality of IDT’s audio solutions brings consumer electronics level per-
formance to notebook and desktop PCs. 92HD71B5 is designed to meet or exceed premium logo
requirements for Microsoft’s Windows Logo Program (WLP) 3.09 and revision 4 as indicated in WLP
3.09.
The 92HD71B5 provides stereo 24- bit, full duplex resolution supporting sample rates up to 192kHz
by the DAC and ADC. The 92HD71B5 SPDIF outputs support sample rates of 192kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
The 92HD71B5 supports a wide range of mobile and desktop 4 channel configurations. The 2 inde-
pendent SPDIF output interfaces provide connectivity to Consumer Electronic equipment like Dolby
Digital decoders, powered speakers, mini disk drives or to a home entertainment system. Simulta-
neous WLP compliant HDMI and SPDIF output is possible. All analog input pairs support LINE_IN
and MIC.
MIC inputs can be programmed with 0/10/20/30dB boost. (40dB boost is available using the IDT
driver.) For more advanced configurations, the 92HD71B5 has up to 8 General Purpose I/O (GPIO).
The port presence detect capabilities allow the codecs to detect when audio devices are connected
to the codec. The fully parametric IDT SoftEQ can be initiated or disabled upon headphone jack
removal and insertion for protection of notebook speakers.
The 92HD71B5 operates with a 3.3V digital supply and either 3.3V, 4V, 4.75V 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.
Available in a 48-pin QFP or QFN Environmental (ROHS) packages.
