Wireless audio streamer
20 July 2011, Telecoms, Datacoms, Wireless, IoT
New from Nordic Semiconductor is the nRF2460 audio streamer IC offering power optimisation and performance specifically for cost-sensitive, battery-powered mono wireless audio applications such as microphones (eg, home karaoke and conference), subwoofers (home cinema), musical instruments (wireless audio adapters) and gaming (eg, singing game mics).
The device delivers a combination of 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 optimised adaptive frequency hopping (AFH) protocol and 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 chip performs smart retransmission of lost packets and suffers minimal audible effects from lost data. The 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.
