TMS320DM6467 Design

ANS

Hi,

We're currently using TMS320DM6467 processor on one of our new designs. We have the following questions related to the Davinci Processor

1. We're not planning to use the Ethernet interface and VLYNQ interface

on the TMS320DM6467. Can the pins be left as no connects or do we need

to connect pull-ups for some of them?

2. Is there any termination length requirement for the J19,J21 and R19, R21 pair?

Thanks

2. Terminators are not required.

For input pins: Pins can be left floating if the IO buffers have internal pull ups or pull downs. If not then they will have to use ext. pull up or pull down.

For output pins: Pins can be left floating.

Power and Gnd pins: All power and Gnd pins have to be connected to correct voltage rail and Gnd.

Regards, Srirami.
