Hi Shimawaki,

As per the datasheet section 8.6.2, default POR register values, all CLKout are powerdown.

But POR default sets OSCout to buffered OSCin and format to LVPECL, which can be used as clock during power-on.

Hi Ajeet Pal,

Thank you for your support.

Is there a way to output CLKout0-13 without setting from SPI after Power-On?
Is it possible to program to turn on CLKout0-13 after Power-On using TICS Pro etc.?

Regards,
SHIMAWAKI

Hi Shimawaki,

CLKout0-13 are not possible to turn-on without programming after POR.

TICS Pro is a tool, which program the device through SPI interface. Yes, after Power-on, you can program the device and make it enable CLKout0-13 using TICS Pro.
