e2e,
We have a condtomer that is evaluating the LMK03002 using the LMK03002CEVAL. This customer's application requires that the input to the LMK03002 be turned off. When the customer does this the LMK03002 still outputs a signal. Here are further details from the customer:
Step1: We had programed the EVAL Kit Fout output @ 1680MHz, Osc port connected to an external source @ 70MHz. We are also monitoring CLK0 -CKL3 output.
Step2: Then we powered the board down for say 1 min,
Step3: Power up the board again
We noticed
Step 4: Switched on the Oscillator reference @ 70MHz and got the following output
Step5: We re-programed the EVAL Kit vi UWIRE for Fout o/p @ 1680MHz, Osc port still connected to an external source @ 70MHz.
Step6: Switch off the Osc port still connected to an external source @ 70MHz. Still have the following outpput:
Question: What's the VCO locking into after input ref is switched off
Thanks for your help.
Regards,
John Wiemeyer
