pump/LDO
Combo Jack Support allowing for dual-function
headphone and headset detection
Full HDA015-B low power support
Internal digital core LDO voltage regulator
Microsoft WLP desktop premium logo compliant
Dual SPDIF for WLP compliant support of
simultaneous HDMI and SPDIF output
Support for 1.5V and 3.3V HDA signaling
Two digital microphone inputs (mono, stereo, or
quad microphones)
High performance analog mixer
2 adjustable VREF Out pins for analog microphone
bias
5 analog ports with port presence detect (4 single
ended, 1 BTL)
Analog and digital PC Beep support
AUX Audio Mode for playback

SINGLE CHIP PC AUDIO SYSTEM, CODEC+MONO SPEAKER AMPLIFIER+CAPLESS HP+LDO
Full HDA015-B 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
Software Support
Intuitive IDT HD Sound graphical user interface that allows configurability and preference set-
tings
12 band fully parametric equalizer
• 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
• Enables improved voice articulation
• Compressor/limiter allows higher average volume level without resonances or damage to
speakers.
IDT Vista APO wrapper
• Enables multiple APOs to be used with the IDT Driver
Microphone Beam Forming, Acoustic Echo Cancellation, and Noise Suppression
Dynamic Stream Switching
• Improved multi-streaming user experience with less support calls
