Hi Champs,
The HDMI_EXTSWING PIN is recommended to connected with external 5.9KΩ resistor with TRM SPRS614D version, while 698Ω resistor was recommended on older TRM version.
Could customer continue use 698Ω resistor on their hardware design? What's the impact on different resistor value and any risk on 698Ω design?
Thanks a lot for support!
Jane
Hi Jane,
I highly recommend to refer to the latest documentation and use the 5.9k resistor. You could also check that the EVM uses 5.9k (see page 11):

Hi Joyce,
Customer wants to know what is function of HDMI_EXTSWING pin?
It affects both the output swing and the Voh & Vol levels. Actually this should be 6.8K ohm. Take a look at the following wiki:
Also this E2E thread:
