SN75LVDS83/SN75LVDS86 Pair

Other Parts Discussed in Thread: SN75LVDS83

 

The SN75LVDS83 and 86 pair is an 18 bit LVDS chip solution.

I am using A 4.3” TDT display which is 24 bits.

 Now, I could ground two pins and go 18 bit on the display and only use 6 bits from the MCU but I don’t know the implications of that?

So, does TI offer a 24bit to 24 bit solution?

 

Q2) why are there 3YM and 3YP pins if they aren’t transferred across the cable?

Are they used in another application that is unique and not common, thus not shown.

 Also, is this the best pair of parts that I should be looking at if it’s TI?

What is the longevity? Is it for new designs? Etc….

 Thank you!

    Ali,

    The LVDS83 (recommend the LVDS83B as the newest member of the family) family is 24-bit RGB capable - the LVDS82 is the corresponding receiver.

    What resolution are you trying to support with your display.  For most smaller displays, the sub-LVDS family, LVDS30x is more typically used.  I would recommend looking at the LVDS 301/302 pair as well.
