AD9910 async parallel port write

In the AD9910 datasheet pg21 says ""the user can drive the TxENABLE pin with a clock signal operating at the parallel port data rate..."

 

1. Does this mean that I can use TxENBALE as an strober for the data port?

     The problem is that the update of the FTW should be synchronized with an external clock, and if I do it using the 250MHz, I would have a jitter of         +-4nS wich is not allowed by the application.
