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, 48kHz. 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 latest 4Mbit/s MegaZtream™ platform embedding a state-of-the-art Quality of
Service (QoS) subsystem, with an ultra-low power robust 4Mbit/s wireless 2.4GHz transceiver and
all appropriate digital audio interfaces, creating a complete digital wireless audio streamer solution
in a 6 x 6mm package. In addition to streaming audio up to 4Mbit/s, 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 A/D and D/A converters for analog 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.
The circuit has embedded voltage regulators, giving maximum noise immunity and operation
from a single 2.0 to 3.6V supply. |
