nRF24Z1 is a unique single chip solution for wireless streaming of crystal clear CD quality stereo audio up to16-bit 48 kspl/s without using any compression. The nRF24Z1 also features input support of up to 24 bit 96 kspl/s. Operating in the global 2.4GHz band the nRF24Z1 offers unrivalled performance and integration coupled with an ultra low solution cost. Based on the Nordic MegaZtream" architecture the nRF24Z1 provides all Quality of Service (QoS) needed through the use of extensive on-chip hardware and firmware resources, to ensure high quality transmission of audio. In addition to streaming audio up to 4Mbit/s the nRF24Z1 also boosts a digital control information channel for transfer of control information such as volume, balance and display information. Using industry standard I2S and S/PDIF interfaces for audio, the nRF24Z1 can interface without gluelogic to virtually any digital audio source, or external industry standard low cost A/D and D/A converters for analog audio input and output. Control information uses SPI or 2-wire (I2C compatible).
