LiDAR Platform
Light Detection and Ranging Platform
Product Overview: high-performance evaluation system for validating a custom LiDAR ASIC. Engineered to bridge the gap between silicon prototypes and market-ready applications, the platform provides a stable, high-fidelity environment to characterise ASIC performance and serves as the reference architecture for all subsequent product integrations.
Technical Solution: the architecture utilises a high-density, multi-board configuration designed to maintain signal integrity across complex interconnects. The core system integrates a high-performance FPGA in a fine-pitch BGA package, managing massive data throughput from the LiDAR front-end. To support data rates up to 5 GHz, the design employs advanced multi-layer stack-ups and spesialised high-speed board-to-board connectors, ensuring seamless mixed-signal isolation and minimal impedance discontinuities.
Core Competences:
- Ultra High-Speed Design: signal conditioning and routing for interfaces up to 5 GHz.
- Complex Interconnects: high-density, multi-board system integration.
- Advanced Packaging: expert BGA escape routing and thermal management for high-power FPGAs.
- Mixed-Signal Precision: isolation of sensitive analog LiDAR returns from high-speed digital noise.
- Interface Standards: LVDS, Gigabit Ethernet, and custom high-bandwidth buses.
Professional Scope: project focused on recovering a design suffering from critical signal degradation. A comprehensive Signal Integrity (SI) and EMI audit has been performed to stabilise the 5 GHz data paths, transforming a failing prototype into a high-reliability platform.
- Design Remediation: conducted a deep-dive analysis and modification of the schematics and PCB layout, implementing advanced impedance matching, stack-up optimisation, and EMI mitigation strategies.
- Systems Integration: worked in direct synchronisation with the System Engineer and Project Manager to ensure all hardware improvements aligned with system requirements and hit aggressive development milestones.
