Infotainment/Cluster

Infotainment/Cluster

Modern infotainment/cluster applications rely on multiple displays, use various interfaces such as USB, PCI-Express and Ethernet, and are increasingly integrated with other domains within the vehicle. As a result, more clocks are needed, with additional requirements such as extended temperature range, high reliability, low jitter, and low power.

SiTime MEMS oscillators offer low jitter, higher accuracy over temp from -55 to 125°C, reliability up to 50x better than quartz crystal devices, and unique EMI features – all in a small package. Our solutions have excellent stability during rapid temperature change (dF/dT) and are resilient against shock and vibration.
