Can TS3V713EL 1:2 VGA switch with integrated level shifting on Hsync and Vsync be used in 2 source/1 end point application?

Other Parts Discussed in Thread: TS3V713EL, TS3V712E

Hi team,

The TS3V713EL datasheet claimed the function of switching between a single VGA source and one of two end points. Is it able to switch 2 sources for 1 end point?

Thanks.

Mike,

Yes, the TS3V713EL is able to switch 2 sources for 1 end point on some of the signal paths but the TS3V713EL has integrated level sifters on two of the signal paths that are unidirectional. If you would like to have a bi-directional type of switch on all the channels you can use the TS3V712E that does not include the level shifting feature.

Thank you,

Adam

Hi Adam,

Looking at the logic diagram, the Hsync/Vsync signal is buffered to two end points. I'm wondering if these two bits can be bidirectional.

could you please give me a update ASAP?

Thanks.

BR,

Mike

Customer used Pericom’s p2p device to do the Demux function. But they found the Hsync/Vsync can’t be bidirectional. Now they want to know if TS3V713EL can do it. Could you please double confirm that the Hsync/Vsync can also be bidirectional? the block diagram in datasheet is not signal switch structure.
Besides, in the TS3V712E datasheet, the Hsync/Vsync are signal switches. If 713EL can't be bidirectional, they would use 712E instead.

Thanks

Mike,

The TS3V713EL integrated level shifters are unidirectional. This means the Hsync/Vsync signal paths are not bidirectional in the TS3V713EL.

If you would like a similar device that is bidirectional on all signal paths I would look at using the TS3V712E device.

Thank you,
Adam
