Audio
It goes without saying that with its skilled team of RF engineers, LM also makes excellent audio products. What doesn’t go without saying, however, is that we also utilise a variety of silicon vendors and technologies to offer our customers the best solution possible, anywhere from a low-bitrate mono audio over Bluetooth® low energy, to aptX® high-quality stereo audio over Bluetooth® v2.1, v4.x + EDR.
LM’s hardware origins spur from its Bluetooth® adapters that utilise Cambridge Silicon Radio (CSR) silicon. CSR is sole the inventor of the renowned aptX® high-quality Bluetooth® audio streaming technology that is found within almost all high-end smartphones and Bluetooth® enabled speakers, headphones and earphones on the market today. LM offers a variety of audio modules within its line-up based around CSR silicon and its associated leading-edge Bluetooth® audio technologies.
In the near future, LM will be expanding its audio range to include products from Broadcom, specialising in high-quality and lossless HD audio streaming over WiFi, including multichannel 5.1. Broadcom have a proven track record for working closely with large corporations to ensure the best possible support for their propriety profiles, such as Apple AirPlay™ and have chosen to extend this same level of support to LM Technologies, who are also a member of the Apple MFi program.
Our LM745 Bluetooth® Audio Module features an on-board DSP for intensive audio codec processing, including support for aptX®and a high-quality 95dB SNR DAC.
Supported profiles include HFP, A2DP, AVRCP, SPP and PBAP, many of which are accessible via an easy-to-use AT Command firmware.
In additional to its analog interfaces, audio can be channelled over PCM, I²S, SPI and UART, making the LM745 ideal for any scenario.
