hello
we are using LMK04826B in one of our application. so i want to configure the LMK by giving 100MHz external source to oscin .
1). I tired configuring LMK in single loop mode by setting oscin source as independant ,feeding single ended clock of 100MHz (1Vpp -sine wave/square wave) and output are recorded but if i remove the clock source the output are present and i programmed LMK with same congiuration reg value without clock source input then also the output are recorded. so how can we justify that input source has an effect on output clock that are being generated?
2)i tired configuring LMK in dual loop mode by giving same input to clockin and observed the same result as( I)
3) how to Configure lmk using external clock source for oscin and clkin single ended input ?
4)can i configure LMK in dual loop mode by giving clock input to OSCIN ?
note :the above experiment has been carried on lmk04826B evm board and i hav attached the config file for single loop .
