Two independent pairs of DACs and three independent pairs of ADCs support multi-Streaming and Real Time Communications applications. The audio fidelity of the device exceeds Microsoft Premium Logo requirements. Two ProCoustic capless headphone drivers deliver 31 mW per channel into 32 Ω loads and eliminate external DC blocking capacitors. Built-in support for 4-conductor-type headset combo jacks saves space and system BOM cost. Multiple stereo Line Outputs are available as well as multiple retaskable ports including Microphone/Line in, Microphone/Line In/Line Out, and Line In/Line Out retasking. Microphone/Line In/Headphone re-tasking is also supported. All output ports feature PopShield technology that eliminates pops and clicks. The codec includes one SPDIF output and one SPDIF Input both supporting sample rates up to 192 kHz, 16-24-bit resolution. Multiple GPIO's are provided, including speaker mute and EAPD functions. Hardware volume control support push button and rotary volume knobs. Integrated 5 V to 3.3 V and 3.3 V to 1.8 V Low Dropout (LDO) regulators guarantee high performance analog audio and clean power to internal digital blocks. Conexant's D-Flex power management allows the system to exceed the power savings specified in the Intel ECR 15B. The internal Wake-on-BEEP logic resumes the analog paths for the PC BEEP to the output ports. Analog and Digital power rails can be dropped in S3/S4/S5 to maximize power savings and EuP compliance.
