• No external termination resistors are required on the DMD_HSSI or DMD_LS differential signals.

• Include a series termination resistor (with a value of 30.1Ω, for example) to the DMD_LS0_RDATA and

DMD_LS1_RDATA single-ended signal paths. Place the resistor as close as possible to the corresponding

DMD pin.

• The DMD_DEN_ARSTZ does not typically require a series resistor; however, for a long trace, one might be

needed to reduce undershoot or overshoot.

9.1.9 General Handling Guidelines for Unused CMOS-Type Pins

To avoid potential damage to unused video source inputs and unused GPIO, the instructions specifically noted in

the associated Section 4 must be followed. For those unused inputs without specific instructions, TI recommends

that these input pins be tied through a pullup resistor to its associated power supply or a pulldown to ground.

Unused output-only pins can remain open. Never tie unused output-only pins directly to power or ground.

For controller inputs with an internal pullup or pulldown resistor, it is unnecessary to add an external pullup

or pulldown unless specifically recommended. Internal pullup and pulldown resistors are weak and cannot be

expected to drive the external line. When external pullup or pulldown resistors are needed for pins that have

built-in weak pullups or pulldowns, use the value specified in Table 4-14.

There are also power supply considerations that must be followed for any unused video sources. These are

detailed in Section 8.3.
