DS90UB947-Q1: single lane mode

Ivy Jin

Part Number: DS90UB947-Q1

Hi team，

My customer uses 947 and it works in the single lane mode, transmitting signals only via D0-D3, D4-D7 are not used. So in this case, how should the pins of D4-D7 be set, suspended, pulled up, or connect to GND?

Thanks in advance!

Regards,

Ivy

Hello Ivy,

unused Inputs can be left as NC, or you can terminate each pair with a 100ohm differential termination.
