Hi Bertl!
11:30
masplund
Bertl: You mentioned, that you could send us a sensor PCB samle, that would be great.
11:34
Bertl
yes, you just want the PCB or an assembled version? :)

Bertl: the PCB would be sufficient, I'm afraid we have too little time to wait for the assembled board.
12:04
Bertl
okay, no problem
12:04
masplund
Do you have the most recent design files available? We are thinking about the reuse of your design for the gamma, but we are a bit hesitant regarding the cooling of the sensor board when the convection air flow is stopped by the horizontal connector setup.
12:05
Bertl
yes, the cooling happens on the front of the sensor board
12:05
Bertl
so the connectors shouldn't be a big problem

Bertl
the v0.13 sensors boards are the current version
12:11
masplund
Depending on the sensor mounting in the gamma camera, I'm not sure we can get all the cooling done on the front side
12:11
masplund
Thank you for the link!

masplund: I think the sensor has to attach to the optical base anyway, so IMHO it would make perfect sense to attach it _with_ the cooling solution, e.g. a heat sink
13:00
Bertl
the entire front of the PCB doesn't carry any parts, so it can be used for such a construction

masplund
ok, if we can do this there is no explicit need to have convection behind the sensor, of course we still have to cool the pre-processing board but maybe we have all 'hot' parts on the other PCB side or we make a heat sink plate for such critical parts.

that's the basic idea, yes

hi all
14:51
Bertl
hey Francky!
14:52
Francky
hey Bertl ! I have worked on the sender/receiver with par to ser an ser to par IP
14:53
Francky
do you agree with me that i need to send 3 inforamtions : data, bit clock and word clock through the lvds/serial lines ?
14:56
danieel
there is only a word clock
14:57
danieel
you recover the bitclock by multiplication of it, in a pll, phase of the clock/data then does matter (same length rule on the PCB)
14:58
Francky
yes indeed !!!!!! in fact i was sure that i need the bit clock, but i was blocked by the need of the word clock, but indeed with only the word clock it is sufficient !
14:58
Francky
