Module bluetooth CSR64215
This module provides your audio installation with Bluetooth 4.2 connectivity. Its embed technology Apt-X allows it to receive audio streams with an almost insignificant loss rate. This encoding / decoding technology is automatic, which means the card will automatically adjust the compression transfer depending on the audio file type. This minimizes the loss to an almost imperceptible level of FLAC.
Conversely, when an already compressed audio file is submitted, this Bluetooth Module automatically detects and adapts to not to apply additional compression. MP3 files less than 350kb / s will thus be transmitted as is without any treatment so as not to denature the audio definition.
Bluetooth optimized for DAC 100mHz (ESS Sabre)
The Bluetooth module is equipped with an I2S output with a 100 mHz fixed MLCK (compatible ESS 9018, 9028, 9038), so it can connect directly to a Sabre DAC equiped with this kind of input in order to enjoy both wireless connectivity and high-quality conversion.
The output MCK (MasterClock) supplied with 5V enables it to significantly reduce jitter for a result well above the ordinary Bluetooth connectivity.
