Part Number: TMDS351
Other Parts Discussed in Thread: TMDS361B

the datasheet mentioned 12bit color depth.

Is it for each color? Hence 36bit

Hi,

It also depends on the chroma subsampling. If the subsampling is 4:4:4, then it is 12x3 = 36 bits per pixel.

Thanks

Hi,

Please see the Switching Characteristics spec in the TMDS351 datasheet. Once the TMDS351 switches from one port to the other port, the source supplies 5V to the sink. The sink will only drive the HPD high once its EDID is ready. The source will sample the HPD high and then read the sink EDID, and outputs the video. So the time will vary from source to source, and from sink to sink.

Thanks

David

thanks again for your paitence

If two of the inputs are DVI FHD and the other is HDMI will it work fine?

Hi,

The audio is not being supported by the DVI.

Also the DVI doesn’t support HDCP encryption by default, so you may not be able to play back full HD Blu-rays and other HD content.

Thanks

Hi David

I saw there is a pin-compatible TMDS361B with adaptive equalizer, Does TMDS361B have an enhanced temperature too?

Hi,

The TMDS361B is only available from 0 to 70C.

Thanks
