In the evaluation board(EVAL_ADAU1962A) in place of decoupling capacitors (10uF -5 nos &0.1uF- 6 nos(Analog), 10uF -3 nos &0.1uF- 3 nos(Digital).
since there are space constraints for my board design.Kindly clarify whether these many capacitors are required else mention the minimum recommended value of decoupling capacitor required for Analog & Digital.
Thanks for quick reply,
Yes i am considering RFI/EMI emission.that's what i asked you how to terminate that LF pin.Kindly give the any suggestion.
1) You can leave the LF pin floating. I suggest you power down the PLL in the Block Power-Down AND Thermal Sensor Control 1 Register.
If you have to terminate all pins for RFI/EMI reasons then ask this question again and I will talk to the PLL designer about it.
2) Thank you for pointing this out. The Theory of operation is correct but the translation from Vrms to Vp-p in the specifications is not correct. It is showing the Vp value. To calculate the peak-to-peak value you multiply the RMS values by 2.828. So it should be the following:
Differential = 2Vrms = 5.66Vp-p
Single Ended = 1Vrms = 2.83Vp-p
I will have to submit a new revision to correct this. It is the same in the ADAU1962A datasheet.
