This application note is an introduction of the CS2100 from Cirrus Logic. Growing demand for audio and video features such as DVD playback, cameras, remote amplifiers, navigation, and rear seat entertainment have created the need for a time-synchronized automotive network. Point-to-point solutions require expensive and complex cabling, and alternative networking architectures such as MOST (Media Oriented Systems Transport) are based on proprietary standards and offer only a single source for hardware.
The CS2100 provides a unique combination of low-input frequency reference, high-factor clock multiplier, extremely low jitter, and low cost. The flexible architecture combined with convenient configuration options make the CS2100 the optimal solution to generate an Ethernet AVB slave node media clock.
