Hello,

we have purchased the TMDS181RGZEVM kit and we need an utility called "Eye Scan" to evaluate this module.

Please provide a download link or email me the software.

Thank you in advance!

Our company firewall blocks .exe whether it's renamed or even renamed inside a zip file, it's a pain. I'll change my email in E2E to use my personal gmail address. Could you please send it again in 5 minutes. Thank you so much.

Can you please send me the Eye Scan software as soon as possible to Eric.Hereford@stryker.com. I recommend that you make this software readily available on line as no engineers like having to log into a site and have someone email them the software.

Hi Eric,

I will provide EyeScan Tool by email. We are still working in the final version that will be available in ti.com

Hello,
I would also like to get the Eye Scan tool to assist with a TMDS181 design. Where can I find the tool and any supporting documentation.
Thanks,
Kevin

Hi Moises,
Can I also get a copy of the Eye Scan software? Or if it's now available on ti.com can you send a link? I've looked but was unable to find it.
Thanks in advance,
Kevin

Hi Moises,

Have you send me the EyeScan tool? I think I have not received further email from you.

Thank you very much!!!

Hi Wee Chang Liew,

I sent you the tool on Tuesday 10/11, around 8:45 USA central time to the email registered in E2E.
Does you mail server has a block for .exe attachments?

Yes, most probably. Possible to rename the attachment or zip it?

Thank you vey much!!!

Hi Moises,

I used the TMDS181RGZ EVM and tried to run the eye scan tool. I am able to output a video from a camera source into a monitor via the EVM. However, I couldn't get any waveform when I run the eye scan tool scan. I follow the default jumper setting from sllu228a.pdf (figure 1). Our source is using HDMI 1.3a, is this an issue?

Thank you.

0 Moises Garcia over 9 years ago in reply to Peck

TI__Mastermind 23815 points

Hi Peck,

When you run eye diagram, do you see at least a horizontal line?
Are you able to read the registers?

Using an HDMI1.3a source shouldn't be a problem.

0 Peck over 9 years ago in reply to Moises Garcia

Hi Moises,

The EVM setting:
J1 -> 2~3
J6 -> 1~2
J4 -> 1~2
J3 -> 1~2
J8 -> 1~2
The rest NC

I am able to read registers and see a horizontal line.
There is something I notice:

1) At the register map, when I try to write a bit (ie page 0, bit 0 at address 00 or any other bit) it will always return to the original value after clicking on the write button.
2) If my equalizer is set to fixed, I try to change any information & apply changes but it will always return to the original value.

There are some control in the <HDMI control> I couldn't set but some I can set.
Is this normal?

Thank you.

Hi Peck,

I think I know what is the problem.
Eye diagrams only work when the device is in retimer mode, perhap the resolution you are using is low enough to work in redriver mode only, you can select a higher resolution or forcing retimer mode.

Regarding the register, firt 8 registers are read only, that's why your writing has no effect.
Some other registers are updatable this means, they update from the cconfiguration in GPIO or device self configuration.
So, you may need to set the device in I2C mode(I2C_EN=High) then, write I2C registers like register A bit 7

Hi Moises,

Now I am able to see the scan result after forcing to retimer mode. I have a few questions that required your advice:

1) What is the function of various equalizer FTC? It seems that it has to be set to "135MHz for below 1.25Gbps" then I can adjust the equalizer level.

2) Is the adaptive or fixed mode a preferred method? I see that whether I choose adaptive or adjust the EQ level from lowest to highest does not make any different to the eyes.

Thank you.

0 Moises Garcia over 9 years ago in reply to Peck

TI__Mastermind 23815 points

Hi Peck,

The FTC value select the operating frequency, you can see when EQ level remains the same, but you change FTC, fixed EQ gain varies.

Eye diagrams can't be taken with adaptive EQ

Changing EQ level does change the eye diagrams, you can switch between levels 0 and 15 to see the change.

Hi Moises,

Regarding the FTC, there are 4 options: 5G, 2.5G, 1.25G & <1.25G.

Does it work this way when we change the resolution, we have to set a suitable FTC:

1) HDMI 2.0 4K 60f or 30f -> 5G
2) HDMI 1.4 Full HD -> 5G or 2.5G
3) HDMI 1.3 Full HD -> 2.5G or 1.25G
4) HDMI 1.3 HD -> 1.25 or <1.25G

If we output a HDMI 2.0 4K video but choose <135MHz for below 1.25Gbps> setting, the eye will be badly affected?

On the other hand if we output a HDMI 1.3 HD video & choose <805MHz for 5G> setting, the eye will be badly affected?

Thank you

0 Moises Garcia over 9 years ago in reply to Peck

TI__Mastermind 23815 points

Hi Peck,

We have to review those values but that's a good reference, this is a reference to specification revisions, resolutions and data rates

HDMI 2.0 4k@60Hz -> 6Gbps

HDMI 1.4(1.3) 4k@30Hz -> 3.4Gbps

HDMI1.2(1.1, 1.0) FHD @60Hz -> 1.65Gbps

The data rate doesn't depend on HDMI version only, it depends on resolution, refresh rate, color depth, and chroma sub-sampling, in automatic mode TMDS181 will choose the right data rate range, in fixed mode you have to know what is the data rate and select it.

Choosing the wrong range will have an impact in the eye diagram because EQ is not selected for the desired frequency.
