Bertl > before sending the order of the microzed breakout board, i've made some modification (i've put 3 sata connector from JX2 to JX1)
09:54
Francky
i can share this version with community if you want

11:19
Bertl
Francky: yes, please do so
11:34
Francky
do i send the new version to you ?
11:37
Francky
i don't know if it will be interesting but this version populate more lvds signal of the JX1 bank, without removing any feature
11:45

11:52
Francky
i have also made the choice to use through hole connectors :)
11:58
Bertl
I'd say upload it somewhere, I can host it for you if you like
11:58
Bertl
if you ordered it (or going to) from OSHpark, consider sharing it
12:19
Francky
i think i will use my traditionnal supplier

I had some thoughts about the framing lines: https://docs.google.com/document/d/1pcAeu5SsY933CBefUpTtFDQFWMIuf0OmDzSQdOVZaNs/edit

12:22
intracube
would be interested to hear other views
12:22
intracube
especially from anyone who's used/seen high-end monitor equipment

and do what you want with
12:26
Francky
i will by component to look at the matching holes
12:26
Francky
and then i will order the pcb
12:29
Bertl
copied them here: http://vserver.13thfloor.at/Stuff/AXIOM/BETA/FRANCKY/
12:32
Francky
great
12:32
Francky
do you have any news about the beta boards ?
12:33
Bertl
you mean the interfaces for the shields, yes?
12:34
Francky
i mean the manufactured boards :)
12:34
Francky
you should have them thios week no ?
12:35
Bertl
ah, yes, we didn't receive them yet, but I expect them any day now
12:36
Francky
cooool
12:40
Bertl
interesting choice (regarding the breakout), I'd expected you to go for all SMT to get more room for bottom traces
12:46
Francky
should be better but i was afraid not to be able to solder by hand the sata connectors
12:52
intracube
Bertl: I've got a question about the HDMI ports if you have a minute
12:53
Bertl
sure
12:53
intracube
are they locked to HDMI compliant resolutions (at the hardware level)
12:53
intracube
or could they be made to output a more generic DVI signal
12:53
intracube
which would allow for different aspect ratios/resolution combinations
12:53
Bertl
DVI will always work, even the analog chips support DVI configurations
12:54
intracube
ah nice
12:54
Bertl
but note that the existing recording devices do not support non-standard modes
12:54
Bertl
we learned that the hard way with atomos & co
12:54
intracube
yeah, of course
12:55
intracube
becase afaik, HDMI only supports SD 720x480, 720x576 and HD 1280x720, 1920x1080?
12:55
intracube
*because
12:59
Bertl
I don't have the HDMI specification so maybe, maybe not :)
13:00
intracube
I thought I read those resolutions... somewhere :)
13:00
Bertl
but I think 800x600 should be an HDMI mode as well
13:00
intracube
there are plenty of DVI PCIe cards on the market that seem far more flexible than the Atomos
13:01
intracube
Bertl: why 800x600 particularly?
13:01
Bertl
danieel probably has all the details
13:01
Bertl
just because I remember seeing that odd resolution on HDMI capable devices and it wasn't in your list
13:01
intracube
ah ok
13:02
intracube
http://en.wikipedia.org/wiki/Uncompressed_video#HDMI_Specifications
13:04
intracube
not sure what secondary format means.
13:04
intracube
maybe they're not fully supported on all HDMI 2.0 devices
13:05
Bertl
I presume it is a must vs can
13:05
intracube
yup
13:09
danieel
one mom, pm me to not forget the Q
13:18
Francky
Berlt > i think about the prng sender on the zynq
13:19
Francky
the prng module need to be connected to a par_to_ser module (to translate parallel data to serial) and then to a OBUFDS (which is a Xilinx module i think) right ?
13:28
Bertl
yes, the SERDES
13:30
Francky
does xilinx provide a serdes module or do i need to code one ?
13:30
Bertl
my suggestion is to use 8 bit, which then get encoded to 10 - 16 bits, which are transmitted via the SERDES
13:30
Bertl
there is an example in the *_hdmi code base
13:30
Bertl
(which uses the TMDS encoder 8/10 and the serdes)
