Audio streamer IC delivers class-leading cost and power optimization for mono wireless audio applications
Developed in close collaboration with premier digital audio converter specialist AKM Semiconductor, Inc., the Nordic nRF2460 delivers a 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 nRF2460’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.
Availability and Pricing
The nRF2460 is sampling today and priced at USD $1.50 in 10k shipments. Also available today is the Nordic nRFgo-compatible nRF2460-DK development kit (priced at $99) that enables engineers to quickly evaluate, test, and prototype a wireless audio application based on the nRF2460.
