DLPC3435: Characteristic impedance of parallel interface

Rossinag

Part Number: DLPC3435

Dear All,

Thank you for your support.

This time I would like to ask the characteristic impedance of DLPC3435 parallel interface input signals.

Would you please give advice about the impedance(ohm) for the customer board circuit pattern design? Is 50 ohm OK? If you have any recommendation please let us know.

Best regards,

Thank you for your support.

I would like to ask you DLPC3435 parallel port PCB routing regarding signal lines impedance recommendation. Is 50ohm ok?

If I am missing this information in TI documents, please let me know.

Thank you and best regards,

Rossinag

Rossinag,

Are you referring to the Parallel video lines? Yes, you should impedance match these lines to 50 Ohms. Be sure to reference the layout guidelines in section 11 of the DLPC3435 datasheet for other best practices. (http://www.ti.com/lit/ds/symlink/dlpc3435.pdf)

I hope this helps.

Best Regards,

Philippe Dollo
