1 介绍

NanoHat PCM5102A
  • Matrix - NanoHat PCM5102A是一个最高采样率为384kHz,分辨率为32-Bit的立体声数字音频

解码模块,为您提供数字音频信号完美还原的音乐盛宴。

  • 信噪比112db,失真-93db,直接输出2.1V RMS音频电压。智能静音系统;软斜升或斜降搭配模拟

静音,实现120dB 静音信噪比(SNR)。

  • 板载了VS1838B红外接收头,可用遥控控制。
  • NanoHat PCM5102A和NanoPi NEO/Air的外形尺寸和接口完全相同,可直接堆叠在NanoPi NEO或

Air上。


2 特性

  • 超低带外噪声
  • 可接收 16、 24 和 32 位音频数据
  • PCM 数据样式: I2S, 左对齐
  • 采样率为384kHz,分辨率为32-Bit
  • 板载红外接收。
