ADIN1300 CLK_IN voltage range

In the datasheet, Clock Input Voltage Range (CLK_IN)  is 2.5V(max)

Does this mean I need to input clock signal whose voltage swing is lower than 2.5V?

in that case, what is the minimum voltage range of CLK_IN ?

  • Hello,

    Thanks for your message. 

    The ADIN1300 can support an external clock in the range 1.62V to 3.63V, so can support a clock source from 1.8V, 2.5V or 3.3V.

    The supply to the XTAL circuit is always 3.3V as it is fed from the AVDD_3P3 supply rail.

    We are in the process of revising the datasheets, so this will be updated in the next revision.

    best regards,

    Catherine.
