Hello Brahim,

As you can see in the schematic, at http://pubs.gumstix.com/boards/ALCATRAZ/R3751/B30022.pdf, for Alcatraz it is not. The Alcatraz is a direct breakout from the Overo only USB console, 3.3V, and 1.8V provided. Even these need to be jumped in order to be connected to the Overo. There are also level shifters provided to change logic signal voltage levels.

Thank you for the infos on the new Alcatraz Expansion Board.

For TV_OUT1 and TV_OUT2 signals, can we then assume that the TV_OUT1 is
to TV_VFB1 via a 1650 ohm resistor,  TV_OUT2 is connected to TV_VFB2 via a
1650 ohm
resistor, and TV_REF to the ground using a 100nF capacitor ?

A such configuration as shown in the beagleboard document on
page 76 of 162 http://www.beagleboard.org/uploads/BBSRM_6.pdf

Thank you for your time and help

Best regards
