Hello Patrick,

Since the parallel inputs are open, there is no a hard impedance fix for them, however they must be as short as possible and highly recommended to be length matched. here you go the EVM user's manual, just in case.

Best regards,

Diego.

Hello Diego,

Thank you for your reply. Add one question of TFP401. Do you have design note or layout guide that can provide to customer? Especially for QE and QO RGB pixel output pin design notes. Thank you.
