AWR1642: Question about ripple spec for 1.3V/1.8V power supply

Chris Meng

Part Number: AWR1642

Hi,

In AWR1642 datasheet, we can find ripple spec for 1.3V/1.8V power supply. Customer has some questions on it. Would you pls kindly help?

1. Does the frequency in ripple spec mean frequency of ripple?

2. Why using RMS voltage instead of peak to peak in the ripple spec?

1. Yes, it's a mean frequency of ripple.
2. That is just a nomenclature, you can convert RMS to peak-to-peak.
VPP = VRMS × √2 × 2

Regards,
Jitendra
