SN75DP128A: Switches & multiplexers

Hi, 

What information are you looking for regarding the SN75DP128A?

Thanks

David

do TI have a schematic how to connect the SN75dp128A?

do i need serial 100nf capacitors on input and output?

Thanks

We do not have a reference schematic for DP128, but I can review your schematic.

Both input and output require to be AC coupled. If you are connecting to a DP connector on the input side, the AC coupling caps may already be present at the DP source transmitter, then you do not need the AC coupling caps.

Instead the DP128, have you take a look at the HD3SS213 or HD3SS214?

Thanks

David

thanks

do AUX P and AUX N needs also AC couples caps on input and output?

Hi,

AUX needs to be AC coupled on both the source and the sink side. For the source, a 100k pullup to 3.3V on AUXN and 100k pulldown is required. For the sink, a 1M pulldown on AUXN and a 1M pullup to 3.3V on AUXP is required.

Thanks

David

Hello David,

attached our schematics see on page 22.

the 2 output ports are connected to panel connectors.

please check and advice the correct implementation.smart bb mk2 20489272600_15_12.pdf
