Overview
The CDCE6214-Q1 is a four-channel, ultra-low power, medium grade jitter clock generator designed specifically for automotive applications. It is produced by Texas Instruments and is AEC-Q100 qualified, ensuring it meets stringent automotive standards. This device can generate five independent clock outputs from various input sources, including single-ended or differential input clock sources, or a crystal. The CDCE6214-Q1 features a frac-N PLL, allowing it to synthesize unrelated base frequencies from any input frequency. It can be configured through an I2C interface or via GPIO pins in the absence of the serial interface.
