Hi NXP Support team,


For i.MX8MQ EVK board:

Would you help to explain why 604ohm resistors added at HDMI_TX[2:0] and HDMI_CLK? It that using for offset after AC couple?

Why not 680ohm or 49.9ohm? 


Tough 608ohm is recommended in hardware user guide, would you please share more information from HDMI IP Spec?


Thanks in advance,
