My customer is developing their product with ADV7630.

About using ADV7630, they ask some questions about controlling equalizers.

 

As 6/33 page of your User Guide(UG-399), it seems that pre-programmed for three frequency bandwidth ranges.

And it can support cable length up to 30m.

 

(The ADV7630 features active equalizer for the input HDMI data signals. This equalization compensates for the high frequency losses inherent in HDMI and DVI cabling, especially at longer lengths and higher frequencies. The equalizer is programmable and is capable of equalizing for cable lengths of up to 30 meters to achieve robust receiver performance at even high HDMI data rates.)

But as 33 page of UG-399, for supporting 30 meters, it seems to need additional programing of equalizer.

 

 (The ADV7630 has programmed equalizer settings for three frequency bandwidth ranges. The internally measured TMDS frequency is compared against these limits. The ADV7630 then applies the corresponding equalizer settings according to the detected range.)

 

Q1) For supporting cable length up to 30m, do they need to do additional controlling of equalizers in ADV7630?

 

Q2) If they need, would you let me know how to control equalizers in ADV7630?
