Multimedia / infotainment bus protection

Essential for entertainment and infotainment systems, multimedia buses are a growing trend in vehicles. For these high-speed buses, which often based on consumer network standards, the challenge is to ensure they can survive the harsh automotive environment and as data rates go up so capacitance must come down. So only the best ESD protection is good enough to ensure reliable operation.
