DATASHEET SINGLE CHIP PC AUDIO SYSTEM CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO+I2S 92HD92 Features • 4 Channels (2 stereo DACs and 2 stereo ADCs) with 24-bit resolution • • • Supports full-duplex stereo audio and simultaneous VoIP Provides a mono output 2.1 audio crossover support Description The 92HD92 single-chip audio system is a low power optimized, high fidelity, 4-channel audio codec with integrated speaker amplifier, capless headphone amplifier, and low drop out voltage regulator. Dual High Definition Audio and I2S Interfaces allow for docking and secondary audio support with a single codec. The integrated combo jack allows for dual-function headphone and headset detection. The integrated high-pass and band-pass filters allow for Hardware EQ and speaker protection. The high integration of the 92HD92 enables the smallest PCB footprint with the lowest system audio BOM count and cost. The 92HD92 provides high quality HD Audio capability to notebook and business desktop PC applications. • 2W/channel Class-D stereo BTL speaker amplifier @ 4 ohms and 5V • • 10 band hardware parametric equalizer Hardware compressor limiter • • • • • Capless headphone amplifier with charge pump/LDO I2S support (2 input, 1 output) Aux Audio Mode with I2C Combo Jack Support allowing for dual-function headphone and headset detection Speaker Protection • • Dedicated BTL high pass filter Mono bandpass filter • • • • • • • • • • • www.DataSheet.net/ 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 3 analog ports with port presence detect (2 single ended, 1 BTL) Digital PC Beep support 48-pad QFN RoHS package IDT CONFIDENTIAL ©2009 INTEGRATED DEVICE TECHNOLOGY, INC. 1 V 1.1 1/12 92HD92 Datasheet pdf - http://www.DataSheet4U.co.kr/ 92HD92 SINGLE CHIP PC AUDIO SYSTEM, CODEC+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 settings 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.
