felix_iirc the final module will get some sort of case; i wonder though how the cooling of the fpga should work then19:13
*** se6astian|away is now known as se6astian19:32
Bertlmetal case? ventilation?20:00
felix_i don't know; i'd just use a heatsink and no fan, since the one fan on the zynq board is already quite annoyingly loud20:03
se6astianwhat power consumption can we expect from that FPGA?20:03
Bertlfelix_: the fan situation will improve dramatically in the future20:04
felix_uh, i didn;t do any measurements on how much current the fpga on the prototype of the sdi board needs20:05
felix_very good20:05
se6astianso I would propose to cool the fpga passively by thermally connecting it to its enclosure metal, knowing roughly what power consumption we are dealing with would help though20:15
se6astianbut looking at the trenz module I guess its not that much20:16
felix_about up to 1,2w for the 3 sdi chips combined and maybe 2.5w for the fpga20:20
felix_(not really sure about the latter one)20:21
felix_i currently have no microsoft office installed and last time i checked the xilinx power estimation thing doesn't work with other office programs20:22
felix_hm, ok, seems that the fpga will probably consume less power; maybe 1,5w20:26
se6astianright20:29
se6astianthat sounds reasonable20:30

KjetilWhat kind of package does the FPGA have? Is it plastic or metal ?20:59
felix_some sort of plastic(?)21:01
felix_not one with a metal lid21:01
KjetilThen I guess the heat dissipation is mainly through the PCB21:03
felix_hm, i don't know if that package is flip-chip or wire-bond21:08
Bertl_oOeasy to tell if you check the pinout vs. the bank view :)21:57
Bertl_oO(in vivado)21:57
felix_the chips i consider using are all wire-bond22:19
