Other Parts Discussed in Thread: DS90UB934-Q1, DS90UB933-Q1, DS90UB936-Q1, DS90UB935-Q1
Hey All,
First of all sorry for my maybe newbie question about digital camera protocols anc IC's.
For the first digital camera project at my job I got the task to create an Camera consisting of an Camera pixel array IC and a DS90CR287 and display it's image on a computer screen.
From what I can make of it, from reading intensively on the internet the last week, is that this camera IC output is converted with an DS90CR287 to a Camera Link interface.
The camera IC itself has the next outputs: DATA_CMOS[0:9], LVAL_CMOS, FVAL_CMOS, DVAL_CMOS and TxCLK_CMOS at 3V3.
From what is described in the datasheet of the camera IC this camera has 2 version:
- the color version, based on the bayer color filter principal and a resolution of QVGA.
- the black and white version, with an resolution of VGA.
The DATA_CMOS[0:9] is the 10-bit value of a single pixel, this at 20MHz output clock.
What do you guys think, is my assemtion of the "Camera IC -> DS90CR287 -> Camera Link" possible? Or did I make a miss assumtion?
As my first task with this camera I need to make a system to display the image on a HDMI display from a PC.
If the camera transmit the data in the protocol "camera link", we can use ofcourse a frame grabber to get the data on the computer.
The other examples I can find on the internet always use a FPGA or PCI-express card.
Actually to use an complete FPGA and a frame grabber is total overkill for the demo I need to make I believe.
After a lot of reading about OpenLDI, FPD-Link, Cameralink and HDMI-IC's I have still the one big question: Can CameraLink directrly be coupled to an HDMI monitor with only IC's of TI?
From all the sollutions I saw on the internet is that their is always be an FPGA involved, the FPGA will convert I think somehow the pixel array the input of the HDMI chip.
It will read the camera in per pixel, row per row and the HDMI IC's do expect already all the 3 colors (RGB) at once?
To achieve this the camera link protocol is implemented always in an IP block in the FPGA.
Is their no other solution to directly hook the camera (camera link) up to the HDMI IC's? Or do we always need an FPGA or a PC with framegrabber?
Already many thanks!
