DAC7811:My DAC7811 doesn't work when there are 25 SCLK periods

Part Number: DAC7811

I combind  spartan3E with my DAC7811, when it comes to simulation, everything is ok, and when there are 17 periods of sclk in a period(One period in SYNC=1), it can output something.However, when I change the period to 25 (9 in SYNC=1),it doesn't work!

Here is my simulation:

 

当我SCLK有17个周期时(1个在SYNC=1,剩余16个在SYNC=0),DAC正常工作,但是当SCLK有25个周期(9个在SYNC=1,剩余16个在SYNC=0,就不能工作了)请问这是为什么呢?
