LiDAR

Light Detection and Ranging (LiDAR) is a distance measurement methodology that uses pulsed laser light reflection to make three-dimensional images of a target. LiDAR is one of the key sensing technologies used for detecting objects and determining distances in autonomous driving systems.

Timing is one of the more critical aspects of any LiDAR system. Microchip’s lineup of high-precision MEMS oscillators gives designers the confidence to create systems that are highly reliable and stable in harsh automotive environments. Our Ethernet portfolio, consisting of PHYs and switches, offers the high-speed throughput needed to connect LiDAR sensors within an autonomous driving environment. And to round out the module design, Microchip offers components for power management, control, connectivity, diagnostics and monitoring to develop a complete system.

MEMS Oscillators

Microchip’s MEMS oscillators are designed to meet the stringent requirements of the harsh automotive environment. With quality and performance advantages over crystal oscillators such as DPPM levels that are ten times lower, shock tolerance 500 times higher, and vibration tolerance five times higher, these MEMS oscillators are an excellent choice for automotive applications. Our leading-edge MEMS technology, advanced packaging and innovative Phase-Locked Loop (PLL) design enables us to offer the most stable, reliable and robust oscillators in the industry.
