1.0 Overview
Many system designers require propagation delay performance of LVDS devices over temperature and voltage.
Propagation delay limits presented in the device datasheet and corresponding SMDs sometimes range from 3.0ns to
11.0ns and account for voltage and temperature variations. Often this wide limit ranges makes it difficult to analyze
critical system timing requirements for a narrower temperature and voltage range. The following Application Note
provides a summary of propagation delay values over temperature and voltage for each device in the Aeroflex
Colorado Springs LVDS Family as listed in Table 1.
Note: Data presented in this application note is not guaranteed and is based on device characterization data over
multiple lots.
2.0 Generalized Propagating Delay Values
Data contained below includes AC parameters from the datasheet that do not have notes such as “Guaranteed
by characterization”, “Guaranteed by design”, or are mathematical combinations of other AC values
associated with them. AC switching characteristics of devices listed in table 1 are only guaranteed to the
limits listed in the device datasheet and corresponding SMD. Data listed in tables 2 – 12 below is not
guaranteed.

3.0 Conclusion
As a device manufacturer, Aeroflex Colorado Springs, acknowledges that system temperature and voltage
ranges are much tighter than the limits provided in the SMD and corresponding datasheet. This application
note is intended to aid the user in the design critical system timings as it related to LVDS drivers and
receivers.
