Ultra low power (ULP) RF specialist Nordic Semiconductor unveiled the new Nordic nRF2460 Wireless Audio Streamer IC that offers unique, class-leading power optimization and performance specifically for cost-sensitive battery-powered mono (single channel) wireless audio applications such as microphones (e.g. home karaoke and conference), subwoofers (home cinema), musical instruments (wireless audio adapters), and gaming (e.g. singing game mics).

Wireless Audio Streamer - Low-Power PCM Digital Audio Streaming SystemNordic nRF2460 2.4GHz Wireless Audio Streamer IC delivers up to 100-hours of operation from two AAA batteries and targets cost-sensitive, mono audio applications like microphones, subwoofers, musical instruments, and gaming mics. The nRF2460 delivers crystal clear uncompressed 16-bit PCM digital mono audio – even in challenging RF interference environments – and features an integrated 4Mbps 2.4GHz radio, adaptive frequency hopping (AFH) protocol, and innovative quality of service (QoS) engine, while being priced at just USD $1.50 for 10k volume shipments.

In operation, a 4Mbps 2.4GHz 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 2.4GHz 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 4Mbps bandwidth also provides ample space to support an auxiliary wireless data channel for user control functions such as mute and volume up/down.

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 22ms, a battery operating lifetime of up to 100-hours from two AAA prime cells, and low cost.
