DS26F31MQML: timing jitter propagation delay temperature dependence

Temperature dependence plots such as are included in the datasheet for the SN55182-SP.

Does TI have propagation delay jitter and propagation delay temperature dependence for other devices fabricated with the same technology node and similar design blocks?  Then we could infer the jitter and temperature dependence of this device.

Hi Leif,

Unfortunately not - this device uses a unique process\(uses L-FAST bipolar technology) which is different than other devices - and many of our quad devices such as this one do not include this information. Propagation delay will increase with temperature towards the maximum - we don't have pulse skew data for this device - and its relation is a bit more non-linear but generally will increase with temperature. 

May I ask why attracted you to  this device currently? Depending on use case we do have devices with much more data  and can offer more insight as how to design and how the part will react under different system circumstances- but there are some significant differences that may make a switch unfavorable - so it really is a case by case basis. 

Please let me know!

Best,

Parker Dodson

I need to use some already-designed electronics which use the DS26F31MQML (radhard, space grade option) and now I want to propagate some timing sensitive signals through the electronics.  So I am assembling a timing budget: both fixed delay (including its temperature dependence) as well as jitter.  However other devices which do not use L-FAST may have different temperature dependence of their propagation delay and different jitter properties (thermally induced noise), so those would not be comparable.  Is there a family of other devices which use L-FAST or is this device the only one?
