Other Parts Discussed in Thread: LMH0344

Hi there,

I have the need for multiple resolution support and looking at using these devices.  The datasheets seems to list all the relevant resolutions that I want except for 1024x768@30fps.

Can you confirm if this is supported?

Thanks

    Greetings,

    I did a quick calculation: 1024X768X30 ~ 24MHz Also, if we multiply this by 1.25 to compensate for the blanking interval overhead this comes to 29.5MHz. Given at maximum you could be sending 20 bits per sample, therefore we have 29.5MHz X 20 = 589.824Mbps

    LMH0344 is an SDI equalizer and supports up to 2.97Gbps. So it will be able to support 589.824Mbps you need. Please note LMH0344 is NRZ data thus serial in and serial out with equalization. If possible it would be a good idea if you could please send us overall block diagram of your application to enable us to get a good picture of the overall application.
