Automotive Cameras

Automotive camera modules present several design challenges. Board space is constrained. Environmental conditions include extreme temperatures, fast temperature changes, shock, vibration, and electromagnetic interference. Increasing sensor resolution means higher data rates, which requires low jitter clocking.
SiTime MEMS-based oscillators meet these challenges. They offer small size, accuracy over temperature from -55 to 150°C (even with fast temp ramp), low jitter, resilience to shock and vibration, and EMI reduction features. Our devices have higher quality and reliability, with a FIT rate that is 30x better than quartz crystal devices to help systems meet functional safety metrics targets.
