集成Realtek ALC887 8聲道聲卡參數(shù)

Meets premium audio requirements for Microsoft WLP 3.10
„ Meets stricter performance requirements for future WLP
„ High-performance DACs with 97dB Signal-to-Noise Ratio (SNR), ADCs with 90dB SNR
„ Four stereo DACs (8 channels) support 16/20/24-bit PCM format for 7.1 sound playback.
„ Two stereo ADCs (4 channels) support 16/20/24-bit PCM format recording simultaneously
„ All DACs supports 16/20/24-bit, 44.1k/48k/96k/192kHz sample rate
„ All ADCs supports 16/20/24-btt, 44.1k/48k/96k/192kHz sample rate
„ Two independent SPDIF-OUT converters support 16/20/24-bit, 44.1k/48k/88.2k/96k/192kHz sample
rate. One converter for normal SPDIF output, the other outputs an independent digital stream to the
HDMI transmitter
„ One SPDIF-IN converter supports 44.1k/48k/96k/192k Hz sample rate
„ High-quality analog differential CD input
„ Supports external PCBEEP input, built-in digital BEEP generator, and pass-through function in D3
mode
„ Software selectable 2.5V/3.75V VREFOUT to be analog microphone bias
„ Two jack detection pins each designed to detect up to 4 jacks
„ Supports legacy analog mixer architecture
„ Wide range (–80dB ~ +42dB) volume control with 1.5dB resolution of analog to analog mixer gain
„ Software selectable boost gain (+10/+20/+30dB) for analog microphone input
„ All analog jacks are stereo input and output re-tasking for analog plug & play
„ Built-in headphone amplifiers for each re-tasking jack
„ Two GPIOs for customized applications
„ Supports Anti-pop mode when analog power AVDD is on and digital power is off
„ Supports stereo digital microphone interface to improve voice quality
„ 48-pin LQFP ‘Green’ package, and pin compatible with ALC888 series
