LMX2595: About LMX2595 SEG1_EN register

APPLO ZHANG

Part Number: LMX2595

Hi，

Will SEG1_EN should be set to 0 or 1, when the following conditions：


but from datasheet SEG1_EN should be set to 0.



And manual description is inconsistent with TICS software description.

Thanks!

Hi Apollo,

SEG1_EN should be equal to 1, it is because you have enabled phase sync mode and both of the Output Mux are not set to VCO output.

Thank you very much for the prompt reply, I still have a question：

Referring to the settings in the above figure and the figure below, how do the outputs of different LMX2595 achieve multi-chip synchronization

Hi Applo,

There are some re-clocking circuitries to achieve phase synchronization. The design is TI proprietary, we won't detail it in the datasheet.
