Description :

The ALC887 is a 7.1 Channel High Definition Audio Codec with two independent SPDIF outputs.
Featuring eight channels of DAC support 7.1 sound playback, and integrates two stereo ADC that can
support a stereo microphone, and feature Acoustic Echo Cancellation (AEC), Beam Forming (BF), and
Noise Suppression (NS) for voice applications.

ALC887 is designed not only to meet the premium audio performance requirements in current WLP3.10
(Windows Logo Program), but provides better characteristics for future WLP. That brings user real high
fidelity of sound quality. […]

Features

1. Meets premium audio requirements for Microsoft WLP 3.10
2. Meets stricter performance requirements for future WLP
3. High-performance DACs with 97dB Signal-to-Noise Ratio (SNR), ADCs with 90dB SNR
4. Four stereo DACs (8 channels) support 16/20/24-bit PCM format for 7.1 sound playback.
5. Two stereo ADCs (4 channels) support 16/20/24-bit PCM format recording simultaneously
6. All DACs supports 16/20/24-bit, 44.1k/48k/96k/192kHz sample rate
7. All ADCs supports 16/20/24-btt, 44.1k/48k/96k/192kHz sample rate
8. 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

PT2323 Datasheet

PT2323 is a 6-Channel Audio Selector utilizing CMOS Technology specially designed for Home Theater System. It provides a built-in 2-Channel to6-Channel Translator, which can directly mix traditional stereo channel to simulate a 6-Channel audio output. Single power supply (9V), I2C Bus Interface as well as very low Total Harmonic Distortion (THD < 0.005%) and other features are incorporated into a single chip thereby providing very high performance. Pin assignments and application circuit are optimized for easy PCB layout and cost saving advantages.
