Hi

 

DR_STR_CLK[1:0]

00     Reserved

01     Medium low (2×) for LLC up to 60 MHz

10     Medium high (3×) for LLC from 44 MHz to 105 MHz

11     High (4×) for LLC greater than 100 MHz

 

There is LLC frequency description along with drive strength.

Is it OK to use 01b or 10b for both 480p(27MHz) and 720p(74.25MHz)?

A customer is evaluationg their board with this control and damping resister to have good waveform(no over/under shoot).
