Comparators speed analogue digitisation
New latched comparators are claimed to provide an order of magnitude increase in comparator sampling frequency, enabling very high frequency and accurate digitisation of broadband analogue inputs.
New from Inphi Corp, the 25706CP and 25707CP are 25GHz latched comparators claimed to provide an order of magnitude increase in comparator sampling frequency relative to other commercially available comparators, enabling very high frequency and accurate digitisation of broadband analogue inputs The latched comparator operates at 25GHz (sampling speed) with less than 4mV hysteresis

Inphi Corp is delivering the industry's first register and phase lock loop for registered DIMMs operating at 667 and 800Mbit/s using DDR2 technology.
In addition to speeding the development of new applications, the 25706CP and 25707CP 25GHz latched comparator is ideal for broadband test and measurement equipment, high speed instrumentation, automatic test equipment (ATE), military and telecommunications applications.
SyntheSys Research was among the first customers for Inphi's high-speed latch comparator technology, using the part in its BertScope, for testing high-speed communications systems and components by incorporating bit error rate tester (BERT) functions with sample-rich eye diagram analysis.
"The latched comparator developed by Inphi gives our BertScope product its ultrahigh performance", said Tom Waschura, Chief Technology Officer of SyntheSys Research "Partnering with Inphi to incorporate their technology gives us direct access to phenomenal jitter and noise reducing performance that directly impacts our key performance specifications".
The 25706CP and 25707CP 25GHz latched comparator has better than 200fs random jitter, and has an analogue input 3dB BW of 18GHz allowing users to capture higher frequency signals for digitisation.
Its very low input offset of 1.5mV results in a particularly high level of input sensitivity.
The 25706CP 25GHz latched comparator operates from a single -3.3V power supply and is available in a ceramic land grid array (LGA) package or in die form.
The packaged part is also available on an evaluation board with SMA connectors.
For customers requiring a comparator that operates from a +3.3V power supply, Inphi offers the 25707CP.
The part is expected to sell for $800 in low volume.
