About nRF24Z1™


The nRF24Z1™ is a unique single chip solution for wireless streaming of crystal clear CD-quality stereo audio up to16-bit, 48kHz without using compression. The nRF24Z1 also features input support of up to 24-bit, 96kHz.


Operating in the global 2.4GHz band the nRF24Z1 offers unrivalled performance and integration coupled with an ultra-low solution cost. The nRF24Z1 uses Nordic Semiconductor’s 4Mbps MegaZtream™ platform embedding a state of the art Quality of Service (QoS) subsystem with an ultra low power robust 4Mbps wireless 2.4GHz transceiver and all appropriate digital audio interfaces creating a complete digital wireless audio streamer solution in a 6x6mm package. In addition to streaming audio up to 4Mbps, the nRF24Z1 also boasts a digital control information channel for transfer of control information such as volume, balance and display details.


Using industry standard I2S and S/PDIF interfaces for audio, the nRF24Z1 can interface without glue logic to virtually any digital audio source, or external industry standard low cost analogue-to-digital and digital-to-analogue converters for analogue audio input and output. Control information uses SPI or 2-wire (I2C compatible).


The nRF24Z1 features a well-balanced design where attention is paid to every detail of the audio interface and the challenging tasks of streaming CD-quality audio with no glitches and degradation in performance in the presence of other 2.4GHz sources such as Bluetooth wireless technology. The circuit has embedded voltage regulators, giving maximum noise immunity and operation from a single 2.0 to 3.6V supply.
