Part Number: TMDS171

Hallo all,

about TMDS differential pair inputs of the component,

AC and DC coupled applications can be used?

AC and DC applications require an external different termination network? Wich ones?

Thank you

Hello Domenico

This device works with DC coupled signals. If you want to use AC coupled signals in the input, we recommend using devices like DP159, for this device you have to use .1uF AC coupled capacitors in the input.

Hi Francisco, in AC coupling no additional termination resistors are required after capacitors? Thank you. Domenico

Hello Domenico,

No, they are not. Please, check the Application and implementation section of datasheet www.ti.com/.../sn65dp159.pdf.
