One of my customer is considering to use ADV7613 for his new product.
In his application, need driver LVDS 1920x720 (Ratio 8:3) Panel , is adv7613 can output that resolution?
HDMI Input 1920x720
LVDS output 1920x720
As per data sheet reference HDMI Receiver supports maximum 148.5 MHz TMDS clock frequency. So it can supports up to 1080p, 60 Hz.
If your resolution is under this limit, then it would be supported by HDMI Receiver.
The ADV7613 can output 24-bit OpenLDI data via dual-channel LVDS transmitters, up to a maximum resolution of 1080p, 60 Hz received at the input. The maximum output clock supported by a single LVDS output port is 92 MHz.
I hope that this would answer your question.
ADV7613 Reference Manual at Page 13,14,15,16
It's seem like didn't have any resolution 1920x720 configuration input or ouput.
so maybe it's in reserved option??
Is it customized format? I believe that scripts are available for standard formats 720p.
Hi Jeyasudha.M :
Do the scripts you mentioned refer to ADV7613-VER.1.1c.txt --ADV7613 Design Support Files ？
I have encountered the same problem as you. How did you solve it?
In ADV7613 datasheet manual,they mentioned maximum resolution support as1080p.But in user guide the maximum resolution support is mentioned as 1920x720p.
To add to what Poornima has stated, The basic limitation is that neither TMDS clock or LVDS clock rates must not be exceeded. In this case the 1920x720p60 ~= 91MHz (guess). This works for the TMDS inputs.
The LVDS is limited to 92MHz so the output should be able to handle this depending on your LCD's input requirements and how the data is packaged. See the section on the LVDS transmitter.
Free run will not work since there is no setting for 1920x720.
To select a script I would try both the 1080p and 720p scripts and pick the best one that works. I suspect the 720p script will win since it has the closest matching TMDS clock rate.
Note: we only test/verify the ADV7613 operations with normal CEA861 formats. 1920x720p is not a standard format.
The bottom line is that the ADV7613 is just a serial to serial converter and as long as you don't exceed any clock rates it should work.
Hi GuenterL and PoornimaSubramani
Adv7613 really dose support 1920x720 resolution. Just configure the correct timing.
I have tested the ADV7613 operations 1920x720p resolution.
Thnak you very much.
