If you take a closer look at the spec's you presented, you will notice that the 1/10th duty cycle current is 200mA. That is, your ON pulse must be 100usec and the OFF width 900usec. Little tough, but you can do it. No flicker then!

So, choose the approrpiate timing to be that 1/10th ON and the resistors to give that 200mA and ... wear your sunglasses!

Also there is also the power dissipation of the LED, 125mW. You must never exceed this limit.
