Noise has always been a component of switched mode power supplies and as with most designs there are trade-offs you have to consider for you SMPS design. Paul Greenland, Marketing Director of National Semiconductor gives you a shopping list of items to look out for when designing with switchers, so you can minimize your trade off gotchas.

"Make no mistake about it," says Don Alfano of Silicon Labs, PMBus will forever change the way system power management is implemented, and your next design won't be competitive if it isn't PMBus enabled.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
