250MHz Multi-channel High Speed Analog Front-End (AFE) for LiDAR, 5G and imaging

Overview

The SM-AFE-250M is a high dynamic range wideband 16-channel AFE designed for LiDAR systems. By leveraging Seamless’ patented Switched-Mode Signal Processing (SMSP) technology and cascaded ?? ADC architecture, our AFE seamlessly fits into LiDAR systems requiring only small area and low power. With up to 250MHz input signal bandwidth and 90dB dynamic range, SM-AFE-250M’s over-sampling architecture is extremely well suited for high-resolution LiDAR systems used in drones, autonomous cars and 3D mapping applications, communication and imaging systems.
