SPECIFICATIONS

Description:
This is a response to the dedicated HIFI DAC expansion board designed by the Raspberry Pi. It uses TI's high-end DAC chip (PCM5102A), uses I2S interface, non-USB interface; users can match audio playback system (such as: volumio, Xbmc system) to build their own After the network HIFI player is used for expansion; the expansion board provides two kinds of output interfaces for external amplifiers and other devices. With ityou can get rid of PC power, turn off slow, power supply noise, trouble

Features:
DAC Marine BB (currently acquired by TI) high-end PCM5102A chip, using I2S interface; support 16 to 32-bit audio data format; distortion and dynamics are ideal, support high sampling rate of 384kHz, dynamic range 112dB, distortion -93Db. According to the operation of 120dB, there is no soft rising or falling slope of the acoustic noise signal-to-noise ratio (SNR) and analog squelch.
The PCM5102A integrates a negative charge pump output, eliminating the need for a DC blocking capacitor; 2.1Vrms ground center output; excellent rejection of out-of-band noise. The PCM510xA can drive multiple parallel products by supporting loads as low as 1KΩ. (ie using multiple power amplifiers simultaneously)
Output port with gold-plated RCV two-terminal and gold-plated 3.5mm headphone holder
Use isolated power supply design to isolate the Raspberry Pi power supply from the DAC part of the independent power supply, and the beads do not interfere with each other, get rid of the current sound
I2S interface for direct decoding of digital to analog, non-USB DAC interface, GPIO without PI extension, etc.
Provide DAC power indicator for easy observation of DAC status
The gold plating process is on the PCB board and the arc (the high-end HIFI DAC adopts the curve) to better ensure the impedance continuity of the signal and reduce the reflection and refraction of the signal.
Reserved infrared receiving interface (adding infrared receiving head)
