The mating height of connectors 6060-080-46-00-10-10-PPTR and 6110-080-00-10-PPTR is 6mm.
Connectors JM4 and JM5 can mate also with any 1.27 mm (50 mil = .050") pitch male header connectors with up to 2 × 40 pins.

Traces of differential signals pairs are :
For applications where traces length has to be matched or timing differences have to be compensated, Table 42 and Table 43 list the trace length of I/O signal lines measured from FPGA balls to B2B connector pins.
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.
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.
