Bluetooth Audio SoC
Actions wireless transmission and transceiver series products provide high integration and high performance Bluetooth audio single chip solutions, integrated Bluetooth radio frequency (RF) and baseband, power management unit (PMU), audio codec and MCU. Can be widely used in all kinds of Bluetooth transceiver integrated products, such as gaming earphones and dongle, wireless microphones, conference speakers dongle, communications headset dongle, TV dongle, game-box dongle, intercom adapters, Bluetooth emission slave module, transceiver integrated module, projector/CD/DVD and various devices that require Bluetooth emission (connect Bluetooth headset or Bluetooth speakers) and other low-latency wireless audio transmission and reception products.
The series integrates Bluetooth radio frequency (RF) and baseband, power management unit (PMU), audio codec and microcontrol unit (MCU) modules. Bluetooth transmit power up to 13dBm, receive sensitivity -96dBm, complete specifications, leading performance. Support one to two (connect two Bluetooth speakers or Bluetooth headsets at the same time), support linein, USB, SPDIF (fiber or coaxial), I2S, MIC, SD/MMC, SPI and other audio input sources, support full-format audio decoding, support screen display, compatible with the market mainstream Bluetooth speakers and Bluetooth headsets, Support HFP AG 16K HD call, support two-way 48K HD voice transmission at the same time, compatible with win7/8.1/10/11/MAC and other mainstream operating systems and mainstream call conference software.
ATS3031 integrates high-quality audio codec, ultra-low delay wireless transmission path, ultra-wideband 32K dual-microphone AI noise reduction, DAC bottom noise is less than 2μV, and the Torch 2.4G private protocol can achieve ultra-low latency (the entire link can be as low as 23ms) when connected through dongle. Provide high-quality audio experience and HD call experience while meeting low latency transmission.
The wireless transmission and transceiver chips are mainly ATS3031,ATS2831P(L) and ATS2851.
