Overview
The CDCE6214-Q1 is a four-channel, ultra-low power, medium grade jitter clock generator designed specifically for automotive applications. It can generate five independent clock outputs selectable between various modes of drivers. The device supports input sources such as single-ended or differential input clock sources, or a crystal, and features a frac-N PLL to synthesize unrelated base frequencies from any input frequency. The CDCE6214-Q1 is configurable through an I2C interface or GPIO pins in Pin Mode, making it versatile for different configurations.
