General Info

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.

 

Actions Bluetooth transmission and transceiver integrated series products support Bluetooth 5.3 dual mode , support LE Audio mode, transmitting power up to 13dBm, receiving sensitivity -96dbm, complete specifications, leading performance. Support multi-device connection, support line-in, USB, SPDIF, I2S, MIC, SD/MMC, SPI, and other audio input source, support all formats of audio decoding, support screen, Bluetooth speakers and Bluetooth headset is compatible with the mainstream market, support AG 16k hd calls, 10 / MAC compatible with Windows 7 / software and other mainstream operating system and the mainstream mobile phone, The latency of HFP calls the end-to-end (dongle to the speaker the whole link) as low as 60 ms, The A2DP supports  the LE Audio mode, which allows end-to-end links  latency to be as low as 20ms or less, making it an industry leader. Support two-way HD voice transmission at the same time.

 

The wireless transmission and transceiver chips are mainly  ATS3031,ATS2831P(L) and ATS2851.
