Hi Team,

We are looking for a dual link LVDS SPDT MUX.

TS3DV642 is single link MUX.

Any dual link LVDS SPDT MUX suggestion? Or can we use two TS3DV642 as dual link LVDS MUX?

Thanks

Would you please provide more detail on the system design requirement?

TS3DV642 is a 2:1 SPDT, does this not meet their need? You can also take a look at this link to see the device selection: www.ti.com/.../products.html

Thanks
David

Hi David,

TS3DV642 only has 4 pairs differential LVDS switch, we need 8 pairs differential LVDS switch.
Any suggestion? Or we can use two TS3DV642 to support 8 pairs differential LVDS signal?

Thanks

We will need to cascade to achieve 8 diff pairs for LVDS. Do you need to mux 8 diff pairs to 16 diff pairs?

Thanks
David

Hi David,

Yes, I need to mux 8 diff pairs to 16 diff pairs, and meet LVDS protocol.

Thanks

Unfortunately, we do not have a device that can drive these many diff pairs, you will have to use cascade solution.

Thanks
