TS5MP645: What to do with unused pins for MIPI application?

Part Number: TS5MP645

From email:

----

Team,

I will not use Data Lane 3 and Data Lane 4 on this device. What should I do with the remaining pins on the device? 

  1. Leave floating?
  2. Connect to ground?
  3. Terminate by resistor? (If so, how??)

Regards,

Sonia

  • Sonia,

    Please follow the design procedures stated in the TS5MP646 and TS5MP645 datasheet and connect unused pins to ground with a 50ohm resistor to match that transmission line impedance and reduce reflections back into the device.

    Thank you,

    Adam
