Semtech Corporation and Intel are collaborating to develop optical semiconductor platforms for Light Detection and Ranging (LiDAR). Semtech’s laser drivers and programmable transimpedance amplifiers (TIAs) are being integrated into Intel RealSense LiDAR Camera L515, enabling the creation of power-efficient, high resolution consumer LiDAR.

The collaboration between Intel RealSense technology and Semtech’s Signal Integrity Products Group has focused on enabling the L515 camera to work in very low signal-to-noise ratio (SNR) environments. The TIAs feature low input referred noise (IRN), which in turn allows the L515 to be a power-efficient, high-accuracy LiDAR system at a very high resolution of up to 23 million depth points per second.

The L515 leverages the Semtech TIA’s high bandwidth to deliver high-precision depth and less than 16mm error at max operating range. Coupled with high frequency laser modulation, the L515 demonstrates unparalleled capability to sense small objects as small as 7mm diameter 1m away1 “We have been working with Intel on LiDAR for several years, and Semtech already has two generations of LiDAR chips in production. In addition, we are currently developing future chipsets together for deployment in this new exciting market,” said Gary Beauchamp, executive vice president and general manager for Semtech’s Signal Integrity Products Group.

“Intel® RealSense™ technology has been used to develop products and solutions for use in Robotics, Logistics, Scanning and other computer vision applications. The Intel RealSense LiDAR Camera L515 using Semtech’s TIA technology delivers unparalleled precision and is the world’s smallest, high-resolution LiDAR depth camera, making it suitable for a variety of use cases” said Sagi BenMoshe, chief incubation officer, corporate vice president and general manager, Emerging Growth and Incubation Group at Intel.
