I have a question about ADV7480.
At Hardware Manual P12, it says ADV7480 can support HDMI1.4b.
Can ADV7480 completely support HDMI 1.4b?
> For example , frequency.
High-Definition Multimedia Interface (HDMI) capable receiverHDCP authentication and decryption support162 MHz maximum pixel clock frequency, allowing HDTVformats up to 1080p and display resolutions up to UXGA(1600 × 1200 at 60 Hz)
Seems like your question is incomplete, could you please append the example part that you tried to ask it?
Thank you for your reply.
I think I wrote everything what I want to ask.
I'm asking about ADV7480.
Thank you for your support everyday.
I'm not in a rush but if you can help about this, it would help us very much.
Are you looking anything specifically like supporting resolutions for this part from HDMI 1.4b specifications?
Yes, I think ADV7480 cannot support maximum frequency with HDMI1.4b.
The ADV7480 can support HDMI 1.4b up to the limited pixel clock rate of 75MHz (720p/1080i). It can not support HDMI1.4b at 1080p (148.5MHz)
Is you comment correct?
Is there any other limitation?
Q1) I am not sure where you that text came from, but the ADV7480 is limited to 75MHz pixel rate (720p.1080i)
Q2) I do not know of any other limits other than those listed on the data sheet
It is written in datasheet P1.
Can you check again which resolution does ADV7480 supports with HDMI?
I got it
It means that ADV7480 can support HDMI 1.4b 1080p?
Yes HDCP 1.4 support as stated in the data sheet
The datasheet didnt mention it could support hdmi 1.4b？ how can i confim it could support HDMI 1.4b?and another thing confused me,if the output is 2k or 4k, means the ADV7480 cannt work?Best Regards
HDMI1.4b and HDMI1.4a only did minor modifications to HDMI 1.4, mostly edits, no added features. See the attachment
What's important is the clock rate (165MHz) When you say 4K I assume 4Kp30 which is 297MHz which exceeds 165MHz.
I'm not sure which 2K version you are talking about. Often this is the same as 1080p.
Thanks for your reply!
i had another question , if my hdmi input is interlace，i need the mipi out is Progressive ，can the adv7482/7480 support it?
my last question it means we need de-interlace ,can the adv7482/7480 support it？
The ADV7480 does not have a de-interlacer
