AVB (Audio Video Bridging) protocols have been widely adopted to achieve time and clock synchronization over Ethernet, especially in automotive infotainment systems. CDCE6214-Q1 is a compact and ultra low-power programmable clock generator that supports output frequency tuning with less than 1-ppm step size. With the frequency margining capability, CDCE6214-Q1 is ideal for AVB media clock synchronization. This application report introduces AVB system architecture and explains media clock synchronization design with CDCE6214-Q1.
