nRF24Z1
Low power 2.4GHz RF Stereo Audio StreamerActive
Description
The Nordic nRF24Z1 is a highly integrated 2.4GHz RF Stereo Audio Streamer. It features a 4Mbps on-air data-rate that supports the streaming of un-compressed CD quality audio in full 16-bit 48kHz stereo.
The embedded protocol stack is custom designed for wireless audio streaming and features Quality of Service for up to 1.536Mbps LPCM audio, adaptive frequency hopping, and bi-directional control data link. The nRF24Z1 also supports 32, 44.1 and 48kHz sampling rates, and programmable latency, plus I2S and S/PDIF for seamless interfacing to low cost audio ADC/DACs.
The nRF24Z1 is available in a compact 36-pin 6 x 6mm QFN package.
