Does the HMC540S have an internal charge pump ot the like or is it completely static? Also device matching question.

Thread Summary

The user inquires about the HMC540S's internal charge pump and bit error consistency in parallel signal paths. The HMC540S does not have an internal charge pump, eliminating clock leakage concerns. Using adjacent parts from the same reel minimizes part-to-part variation, ensuring similar attenuation when set to the same bit values.

Does the HMC540S have an internal charge pump ot the like or is it completely static (as long as the bit values aren't changed)?

I'm dealing with very small signals and any internal clock for a charge pump or the like might feed into my signal and disturb it.

Also, would the bit errors of two deviced match somehow, so two parallel signal paths with their attenuators set to the same bit values would experience a very similar attenuation?

It's assumed that they would be populated directly after one another, so the devices would be from adjacent pockets on the reel.

Thanks!
