*Assuming 100% usage of BRAM, LUT, FF. Logic and BRAM clocked at 80 MHz. 9 LVDS in, 14 out, clocked at 320 MHz for Kintex-7 XCK160T in FBG676 package

**Radiation effects on power consumption are assumed small based on additional evidence presented on page 4 of https://indico.cern.ch/event/490512/contribution/0/attachments/1225205/1795163/LHCb_upgrade_elect_110216.pdf

***Power dissipation of GBT-SCA is <50 mW, so has been neglected in this analysis
