DLPC3430: Unused Parallel port connections on PCB

Stephen Craig

Part Number: DLPC3430

Hi,

I'm using the DLPC3430 in a design. I'm currently using the DSI port. Do the parallel port inputs need to be tied to ground when using DSI?

Kind Regards,

Hi Stephen,
Please refer to the note (5) in page 6 of DLPC3430 datasheet www.ti.com/.../dlpc3430.pdf.
It states that :

"(5) Unused inputs should be grounded or pulled down to ground through an external resistor (8 kΩ or less)."

regards,
Vivek
