2.1. Hardware Features
4 Channel High Definition Audio Codec
Meets performance and function requirements for Microsoft WLP 3.10, and stricter performance
requirements for future WLP
Two stereo DAC support 16/20/24-bit PCM for two independent playback (multiple streaming)
Two stereo ADC supports 16/20/24-bit PCM format for two independent recording
All DACs support independent 44.1k/48k/96k/192kHz sample rate
All ADCs support independent 44.1k/48k/96k/192kHz sample rate
Two independent SPDIF outputs support 16/20/24-bit format and 44.1k/48k/88.2k/96k/192kHz rate
All analog jack ports except MONO, BEEP-IN and HP-OUT are stereo input and output re-tasking
Supports line level mono output
Supports analog PCBEEP input, and features an integrated digital BEEP generator
Support two stereo digital microphone input for microphone array AEC/BF application
Each stereo digital microphone interface has its own clock output to support independent sample rate
Supports legacy analog mixer architecture
Built-in five headphone amplifiers on port-A and port-D, port-E, port-F and port-I.
Headphone amplifier on port-I (HP-OUT) is designed to drive output without external DC blocking
capacitors
Software selectable 2.5V and 3.2V reference output for microphone bias
Software selectable boost gain (+10/+20/+30dB) for analog microphone input
Two jack detection pins; each supports detection of up to 4 jacks
Supports two GPIO (General Purpose Input/Output) pins (pin sharing with digital microphone
interface)
Supports EAPD (External Amplifier Power Down) control for external amplifier
Supports anti-pop mode when analog power AVDD is on and digital power is off
Supports 1.5V~3.3V scalable I/O for HD Audio link
48-pin LQFP ‘Green’ package
