Digital Interface WM8804G for Raspberry Pi SPDIF I2S TCXO
This Audiophonics DigiPi+I2S interface expands the output connectivity of a Raspberry Pi, giving it an additional panel of digital audio outputs. It includes a Toslink optical output and a coaxial output, but also an I2S LVDS output via HDMI. Thus, equipped with the DigiPi+I2S interface and an efficient software solution, your Raspberry Pi can be transformed into a real high fidelity network player.
Connecting the Raspberry Pi to the interface is very simple in I2S using the integrated 40-pin GPIO connector.
The DigiPi+I2S uses the HiFiBerry Digi standard. It is therefore compatible with Volumio or Moode Audio, free and extremely complete software solutions based on Raspberry Pi. Each one has many features to enrich the playback. Moreover, it is a software environment specially developed for this type of hardware, so the whole thing will work to the best of its abilities.
To work properly, the DigiPi+I2S needs to use the HiFiBerry driver. This is called HiFiBerry Digi(Digi+) on moOde Audio and HiFiBerry Digi on Volumio.
The interface works with a WM8804G digital chip. It is connected to the Raspberry Pi by I2S via GPIO and the precision of the digital stream is ensured by a TCXO Audiophonics 27MHz 0.1ppm clock. Thanks to this configuration, the interface is able to handle sample rates up to 24bit 192kHz with a particularly low distortion and jitter rate.
In order to give you the freedom to make the best decision in terms of power supply, the DigiPi+I2S interface will be able to adapt to different power supply configurations. The interface and the Raspberry can be powered via a DC 5.5/2.5mm jack input. The reverse is also possible and the interface can be powered directly via the Raspberry Pi GPIO.
Configuration 1 : The Raspberry Pi powers the DigiPi+I2S.
Configuration 2 : The DigiPi+I2S powers the Raspberry Pi.
