Diego,
This is my simple system - if it helps:
http://www.satsignal.eu/ntp/FreeBSD-GPS-PPS.htm
I made a small box so that I could see the PPS signal flashing.
You should be able to get 5V from a USB cable - just cut off the connector
and use the black (0V) and red (+5V) cables. There is plenty of power for
a GPS 18 LVC. More information is here:
