4-CHANNEL HD AUDIO CODEC WITH QUAD
DIGITAL MICROPHONE INTERFACE
92HD005/92HD005D
Description
The 92HD005/92HD005D are high fidelity, 4-channel HD
Audio CODECs that enable 2.0 Audio with simultaneous
Real-Time Communication such as VoIP, conferencing,
voice command and control, etc. Up to four digital
microphones are supported, enabling high quality voice
input for increased usability of voice applications.
Features
• High performance SD technology
• 95dB DAC SNR
• 90dB ADC SNR
• Two stereo DACs and two stereo ADCs
• Supports 2.0 Audio with simultaneous Real-Time
Communication (RTC) channel such as VoIP or separate
stereo audio stream
• Provides mono output for laptop sub-woofer
• 24-bit resolution with up to 192 KHz sample rates
• Supports advanced chipsets with flexible 1.5 V to 3.3 V
signaling
• Digital microphone interface
• Direct interface to up to four digital microphones
• Analog stereo microphone
• Microphone Boost 0, 10, 20, 30, 40dB
• Five adjustable Vref outputs for microphone bias
• Universal Jacks™ functionality for jack retasking
• S/PDIF In and Out
• Two-pin volume up/down control
• Digital PC Beep to all outputs
• +3.3 V and +5 V analog power supply options
Block Diagram
• Optimized and flexible power management
• 48-pin LQFP and 48-pad QFN environmental package
Software Support
• SKPI (Kernel Processing Interface)
• Enables plug-ins that can operate globally on all audio streams
of the system
• 12 band parametric equalizer SKPI plug-in
• 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
• Dynamics Processing SKPI plug-in
• Enables improved voice articulation
• Compressor/limiter allows higher average noise level without
resonances
