HD3SS215: HD3SS215 for eye diagram issue

Kevin Peng

Part Number: HD3SS215

Hello Sir

HD3SS215 compatible with HDMI and DisplayPort electrical standards, does it have support for eye view pass test ?
The silicon datasheet did not see the eye test chart, Can provide eye test pass letter or document from TI ? thanks

Hi Kevin

This is a passive switch, these devices are supposed to behave as a trace with some loss.

You can check Ron and the device losses in the datasheet, there are no eye diagram reports for passive switches.

Hello Kavin

You can check Ron in 7.5 section, in table on page 8. In that table you will see Ron resistance, Ron resistante match between pairs of the same channel, Rflat_on (Ron(max)-Ron(main)) for DA, DB, DC high speed signal Paths. We also have losses described below of this part on next page.

In this case, you are working with a passive switch, then, it depends on the quality of your connector, long and cable quality, long and quality of the trace. I recommend using a high quality cable / connector and short distance.

Please, let me know if you have any other questions.

Regards

Francisco
