The VT1616 integrates 1 Hz resolution VSR on all channels Sample Rate Converters on all channels and can be Integrated IEC958 line driver for S/PDIF output adjusted in 1Hz increments. There is a provision in S/PDIF compressed digital or LPCM audio out hardware for down-mixing the 6 channels into Hardware downmix option to 2 channels stereo when only two end points are available. The ADC DC removal for removing recording white noise analog mixer circuitry integrates a stereo enhancement to provide a pleasing 3D surround 4-bit 3D stereo expansion for simulated surround sound effect for stereo media. This codec is 4 stereo, 2 mono analog line-level inputs designed with aggressive power management to Second line-level output with volume control achieve low power consumption. When used with a 3.3V analog supply, power consumption is further External Audio Amplifier Control reduced. The primary applications for this part are Low Power consumption mode desktop and portable personal computers Exceeds Microsoft® WHQL logo requirements multimedia subsystems. However, it is suitable for 3.3V digital, 3.3 or 5V analog power supply any system requiring 6-channel audio output for home theater systems at competitive prices. 48-pin LQFP small footprint package CENTER + LFE PCM OUT REAR SURROUND PCM OUT PC_BEEP PHONE FRONT PCM OUT SRC LINE CD VIDEO AUX MIC1 MIC2 SYNC BIT_CLK SDATA_OUT SDATA_IN RESET# M U X SRC DAC VOL MUTE LFE/CENTER SRC DAC M U X VOL VOL MUTE MUTE VOLUME /MUTE MASTER VOLUME LNL/SR_OUT Σ MUTE MUTE MUTE MUTE MUTE MUTE LINE_OUT DAC VOL VOL VOL VOL VOL Σ 3D Σ M U X MONO VOLUME MONO_OUT VOL +20dB VOL Σ M U X MASTER INPUT VOLUME AC’97 Digital Interface ADC XTL_IN XTL_OUT OSC PCM IN SRC S/PDIF_OUT Figure 1.
