Ultra-low power clock generator designed for automotive applications

Texas Instruments CDCE6214-Q1 Ultra-Low Power Clock Generators are intended for automotive applications generating five independent clock outputs selectable among various modes of drivers. Other applications incorporate data centre and enterprise computing for PC and notebooks, and multi-function printers.

The four-channel, medium-grade jitter clock generators comprise an input source that could be a single-ended or differential input clock source, or a crystal. These clock generators provide a frac-N PLL to synthesize unrelated base frequency from any input frequency. The devices are able to be configured through the I2C interface. In the absence of the serial interface, GPIO pins can be employed in Pin Mode to configure the clock generators into distinctive configurations.

Providing -40C to +105C temperature grade, supporting 100Ohm systems with low electromagnetic emissions, the device also offers a small footprint on the 24-pin VQFN (4mm x 4mm). The devices are AEC-Q100 qualified for automotive applications.
