DATASHEET
FOUR CHANNEL HD AUDIO CODEC
OPTIMIZED FOR LOW POWER/LOW COST
DESCRIPTION
The 92HD95 is a low power optimized, high fidelity,
4-channel audio codec compatible with Intel’s High Defini-
tion (HD) Audio Interface. The 92HD95 provides high qual-
ity, HD Audio capability to notebook and desktop PC
applications.
FEATURES
• 4 Channel (2 stereo DACs, 2 stereo ADCs) with
24-bit resolution
• Microsoft WLP premium logo compliant
• 2W(4ohm)/1W(8ohm) Class-D Stereo BTL Amplifier
at <1% THD+N and 5V
• Selectable frequency hardware high-pass filter for
speaker protection.
• 10 band hardware parametric equalizer (5 bands per
channel) for speaker optimization in ALL operating
scenarios
• Hardware compressor limiter allows higher average
volume level without resonances or damage to
speakers.
• Integrated Class-G true capless stereo headphone
amplifier with charge pump/LDO
• 4 analog ports with port presence detect (3 single
ended, 1 BTL)
• Combo Jack Support allowing for dual-function
headphone and headset detection
• 2 Voltage adjustable VREF_Out pins for
microphone bias
• 2 Digital microphone inputs (4 mic support)
• Microphone Mute Input
• Selectable 1.5V and 3.3V HDA signaling
• Internal DVDD LDO voltage regulator
• Supports Runtime D3 (RTD3) low power mode
• Capable of MSLync Compliance
• Full HDA015-B and EuP low power support
• Audio inactivity transitions codec from D0 to D3 low
power mode
• Resume from D3 to D0 with audio activity in < 10 msec
• D3 to D0 transition with < -65dB pop/click
• Port presence detect in D3 with or without bit clock
• PC beep wake up in D3
• Additional vendor specific modes for even lower power
• 3.3 V analog power supply
• Digital and Analog PC Beep to all outputs
• 40-pin 5mm x 5mm QFN RoHS package

SOFTWARE SUPPORT
• Intuitive IDT HD Sound graphical user interface
that allows configurability and preference settings
• Output Path Processing
• 12 band fully parametric equalizer
• Compressor/limiter allows higher average volume level
without resonances or damage to speakers.
• Enables improved voice articulation
• Constant, system-level effects tuned to optimize a
particular platform can be combined with user-mode
“presets” tailored for specific acoustical environments
and applications
• System-level effects automatically disabled when
external audio connections made
• Input Path Processing
• 2 band fully parametric equalizer to allow for shaping of
microphone response
• Compressor/limiter allows higher average volume level
• Available near-field and far-field voice capture
algorithms to support conference room/lecture hall
applications
• Microphone Beam Forming, Acoustic Echo
Cancellation, and Noise Suppression
• IDT APO wrapper
www.DataSheet.net/
Enables multiple APOs to be used with the IDT Driver
• Dynamic Stream Switching
• Improved multi-streaming (Real Time Communication)
user experience with less support calls
• Broad 3rd party branded software including
Creative, Dolby, DTS, Waves, Sonic Focus & SRS
