Verifying the true jitter performance of clocks in high-speed digital designs

As the data rates in high-speed digital designs increase, the limits for overall system jitter become tighter. This especially applies to the various components of the clock tree, where the jitter limits for reference clocks, clock buffers and jitter attenuators are even tighter. Due to their high phase noise sensitivity, phase noise analyzers are the […]

Outphasing, Envelope & Doherty transmitter test & measurement

Meeting the efficiency challenge of RF front ends (RFFE) is increasingly difficult at higher operating frequencies and bandwidths, such as those proposed for 5G. There is a group of transmitter RFFE architectures whose signal output is constructed from two, or more, efficiently generated components. The architecture of their signal construction uses predictive, post-correction linearization. Their […]

Verifying additive phase noise and jitter attenuation of PLLs in high-speed digital designs

Increasing data rates in high-speed digital designs and wireless communications require SerDes PLLs and clock synthesizers with low additive phase noise and high jitter attenuation. Modern designs often follow a two-stage architecture, consisting of a jitter-attenuator and a frequency-synthesizer stage. Due to their high phase noise sensitivity, phase noise analyzers are the instruments of choice […]

Get smart with test: Find true cost of ownership

Production test is a necessity that prevents major quality issues in your products that represent the company brand in the hands of customers. The costs, however, can be significant and are often greatly misunderstood. For instance, how would you quantify the positive business impact of high-quality products or shortened time to market? Best-in-class organisations are […]
