The CDCE6214-Q1 is a four-channel, ultra-low power, medium grade jitter, clock generator for automotive application that can generate five independent clock outputs selectable between various modes of drivers. The input source could be a single-ended or differential input clock source, or a crystal. The CDCE6214-Q1 features a frac-N PLL to synthesize unrelated base frequency from any input frequency. The CDCE6214-Q1 can be configured through the I2C interface. In the absence of the serial interface, the GPIO pins can be used in Pin Mode to configure the product into distinctive configurations.
