CERN

  • Open Hardware Initiative (OHI)
  • CERN Beams department
  • BE-CO-HT section
  • Tomasz Wlostowski
  • Javier Serrano
  • Antonella Del Rosso
  • differential pair routing: support fast signals over a long distance and with less noise
  • length matching: two signals take exactly the same time to cross the PCB
  • Push and Shove router
