off to bed now ... have fun!

Hello here

My understanding is you need a XC7Z030-2FFG676 to get a 10Gb/s able GTX

I guess it's a follow up from the amiling list conversation

I'm not competent in pro video to know which features are needed

I take it you're F. Renet ?

I did not introduce myself

it's okay

hi !

http://www.xilinx.com/products/technology/high-speed-serial/index.htm

and for TMDS, I think it mainly depends on the 'other end'

HDMI has 3 TMDS channels, with up to 10.2 Gbit/s

it seems it's the latest one

http://www.xilinx.com/publications/matrix/Product_Selection_Guide.pdf

they are somewhat different, as they have general purpose serial ports (starting with 7030

my understanding is it's possible to have tmds outputs without GTX using oserdes2 outputs but i've to check up to what speed

yes, there are many options, for example, the zedboard (7020) has an analaog devices hdmi chip attached

nice, this last document, which was already pasted somewhere, explains a lot

would be an option, but probably not, the hdmi/display port(s) are probably more usefull for control monitors and viewfinding stuff (where HD resolution is sufficient)

yes, some pros in the field definitely go like "meeeeeeh" when there is HDMI

the conenctors do not cost much, regardless what type whe choose

from the zynq-7k PoV we are limited to the 7030 (last webpack supported device)

I think we should allow for soft reconfiguration of available ports

the user can then configure which physical ports are actually used

(there's some configurations similar to this available on the RED Scarlet, to some extent)

channel link

Camera Link uses Channel Link

ok

OTOH, many manufacturers (NXP, TI, Analog) already provide high speed muxes (up to 16GBit/s)

True

yes

I think I see

haaaa, and that's what you would like to make software configurable ?

I'd say so, but I'm not the right person to ask :)

Alexa, reds, ENG (TV) equipment

If HDMI is "low resolution" limited to full HD I think it's doable without using a high speed serdes

so it's possible to have a 10Gb/s SFP+, 2 Sata and a 3G SDI output

it is a question of available pins and bandwith, we could always add some external serdes

we probably want to use 67 pairs for the sensor chip

Bertl: what kind of "inputs" on the fpga are the pairs connecting to ?

there are dedicated and general purpose pins

the high speed serial ports GBit/s are dedicated ports

there are also a number of peripherial ports (on the zynq-7k) which cannot be used/mapped

like maybe the pci ?

for example, the XC7Z030 (probably our best choice)

comes in three packages, one with 484 pins and the other (probably also our best choice) with 676 pins

ha, now that I look bvetter in the table I can see the "inputs"

they are listed as Processing System User I/Os there

yes, excluding the other pins used for power, etc

but it makes sense to use them wherever possible in the final design

oh okay I see

basically everything which requires higher level decisions

will it handle comuting/enabling of sata drives ? I understand it's far from being there for the needed bandwidth

it will do all the (G)UI stuff, map high speed serial ports and basically decide what gets routed where

yes, I understand that

yes

well I think I learned a lot !

most likely

we need 67 for the sensor as you said

the prototype will do with just 35

yes, exactly have the data lanes (32 instead of 64)

*half

PL == programmable logic ?

well, all this is great

get a zedboard, start hacking on the PL/PS code :)

http://www.zedboard.org/buy

yeah, it's an excellent price for the hardware on that board

http://www.zedboard.org/sites/default/files/Avnet%20ZedBoard%20Brochure%20English%20Version.pdf

PS refers to the hardened arm cores and the peripherials

I see

haha, didn't realise I actually read "windows", but indeed it's mentioned there

and also on the pcb layouts for the actual prototype

it could be really great to have sata

not that that wouldn't be a horrible idea

we should poll customers if they'd prefer a Windows CE open source camera :)

well, probably they will, after all, microsoft knows how to please their customers :)

You haven't heard about any because of the non-disclosure agreement you need to sign :P

imagine that, there actually is a WinCE BSP for the zynq

yep, if the camera could be ready for tonight, I'd be very pleased, thanks for your efforts

hehe :)
