HSMT Audio Interface

HSMT-ADIO is an analysis solution developed based on the emerging automotive audio bus HSMT technology, designed specifically to meet the measurement requirements of manufacturers in the automotive and consumer electronics audio industries. This audio interface features flexible HSMT network configuration and rich audio input/output interfaces. Combined with audio test software, it enables efficient audio testing for various HSMT components, such as automotive head units, amplifiers, microphones, and more. In addition, it supports multiple communication interfaces including USB, Ethernet, CAN, etc., making it highly suitable for R&D and automated production line testing.

Key Features

⦁ 8V HSMT bus voltage

⦁ Can monitor HSMT bus current

⦁ HSMT upstream can be output to analog output, S/PDIF output, and UAC input endpoint.

⦁ HSMT downstream can originate from analog input, S/PDIF input, and UAC output endpoint.

⦁ Supports ASIO applications

⦁ Supports 3.5mm analog input and output interfaces

⦁ Supports S/PDIF digital input and output interfaces

⦁ Supports USB-to-serial and Ethernet control

⦁ Supports CAN FD communication up to 4Mbps 

⦁ 32 internal sine wave generators; the frequency, amplitude of each audio channel and the phase difference between channels can be set independently.

⦁ Integrates two 4th-order Delta-Sigma modulators (64x oversampling) with two-channel PDM output capability.

⦁ Facilitates rapid HSMT network setup via the HSMT-ADIO debugging tool or through serial/Ethernet programming.
