85dB SNR (A-Weighting)

 

 

Internal Digital Microphone

 

 

• Two speakers, max. 1W output for each

 

 

• 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
