Clock source of i.MX6 HDMI TMDS and audio clock.

[satoshishimoda]

Hi community,

I have a simple question about the clock source of i.MX6 HDMI TMDS and audio clock.

I guess the clock source of TMDS is video_27m_clk_root from PLL3 PFD1 and HDMI audio clock is regenerated from TMDS with N and CTS.

Is this correct?

Hi Igor,

Thank you for your reply.

Then, would you let me know the tolerance of HDMI audio clock which is made by TMDS clock also?

(e.g. +- xx%)
