CDCE72010 mode running change

Hi,

I have got one question about CDCE72010 mode change.

Is it possible to change the mode from CD-mode to SPI mode?

That is to say, at first, this device is started on "CD-Mode" (MODE_SEL, 16pin = L) and after working start(clock out), then changed to "SPI mode" (MODE_SEL = H).

Is this possible?

And if yes, are the output signals keep stable during mode change?

Thank you for your support.

Hi Takumi-san,

This pin is sample on power up so this functionality is not possible. However, the EEPROM can be configured with a default configuration and then can be changed over SPI when needed.
