Audio streamer delivers class-leading cost and power optimization for mono wireless audio
Developed in close collaboration with premier digital audio converter specialist AKM Semiconductor, Inc., the Nordic nRF2460 delivers a unique combination of crystal clear uncompressed 16-bit PCM digital audio, audio latency as low as 22 ms, a battery operating lifetime of up to 100-hours from two AAA prime cells, and low cost.
In operation, a 4 Mbps 2.4 GHz radio combined with an optimized adaptive frequency (AFH) hopping protocol and unique audio Quality of Service (QoS) engine enable the nRF2460 to maintain robust wireless audio co-existence, even in challenging RF environments that include other common 2.4 GHz interference sources such as Wi-Fi and Bluetooth wireless technology. The nRF2460 includes smart retransmission of lost packets and minimal audible effects from lost data. The device’s 4 Mbps bandwidth also provides ample space to support an auxiliary wireless data channel for user control functions such as mute and volume up/down.
The nRF2460 is available in a compact 6- x 6-mm QFN package and can operate with a single low cost 16 MHz ±50 ppm external crystal. I2S, SPI and I2C interfaces also provide seamless interfacing with external audio ADCs, DACs, and microcontrollers.
