Part Number: TMDS341A Hi Team,
We would like to seek your assistance for clarification.
The HDMI 1.3a, it shows clock rates around 100MHz to 300MHz, On the white paper it states that there are 10 bits per packet. We would like to clarify the real…
Part Number: TS3DV642 Other Parts Discussed in Thread: TMDS341A , , HD3SS215 Hello, we will update a DVI switch that today uses TMDS341A. The idea of the update is better / faster performance. We are now looking at TS3DV642, is this a good choice? Best…
Hi,
i am not sure, what exactly is meant by shielded. The connector has a metal case, which is connected directly to the PCB GND (as well as all other shields). I use this one:

Hello,
This design guide will be helpful not only for inter-pair length matching, but for other HDMI design related questions. 4812.Texas Instruments HDMI Design Guide.pdf
Thanks,

Hello, Steffen,
The output inter-pair and intra-pair skew are correct in the datasheet.
Please also refer to this TI HDMI design guideline. 5684.Texas Instruments HDMI Design Guide.pdf
I would also recommend placing common mode choke on the HDMI…
Hi Barrie,
I'm still checking on weather the EVM had these tests done, but in the meantime without having more details about your exact setup I would recommend you take a look at https://e2e.ti.com/cfs-file/__key/telligent-evolution-components-attachments…
Hi Matt,
Sorry for the delay.
1. The only pin compatible part is the TFP410 but I expect the EMI performance to be the same.
2. I would recommend first focusing on the PCB layout and ensuring you're following proper layout guidelines: https://e2e…

The DP158 equalizer can compensate up to 15.5dB loss on the input side. Please take a look at section 9.2.3 and you can see the DP158 is able to open up the eye after a 20in 4mil trace. On the connector side, it has a 3.5dB pre-emphasis.
Please…
Would you please send the schematic and layout for review? I can see from the picture that the TX2 does not maintain differential when going from the output of the TMDS181 to the connector.
To improve the eye at the output, have you tried different…

Why do you need to design with both TMDS181 and DP159? I am concerned that you might over-equalize the signal with cascading the TMDS181 and DP159 on the same signal path.
For the inter-pair and the intra-pair skew, please follow the HDMI 2…
