The CDCE6214Q1TM is a 4-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 can be a single-ended or differential input clock source, or a crystal. The CDCE6214Q1TM features a frac-N PLL to synthesize unrelated base frequency from any input frequency.
