Traces of differential signals pairs are:
- NOT routed symmetrically (as symmetric pairs);
- NOT routed with equal length;
- routed with a differential impedance between the two traces of 60 ohm.

Pairs of pins that form a differential I/O pair appear colored together in the table. An electronic version of these pin-out tables are available for download from the Trenz Electronic support area of the web site.
Hardware Design Requirement

PUDC_B (pull-up during configuration, active Low) pin in TE0320 modules is hard-wired high, determining user-I/O pins to float before and during configuration. Turning off pull-up resistors in hot-swap or hot-insertion applications, disables potential current paths to the I/O power rail. However, external pull-up or pull-down resistors may be required on each individual I/O pin depending on the specific application.
