Why my AD9747 cannot work?

My AD9747 does not work when powered on, the power sources , input clocks and input data are all good, I controlled the AD9747 thru a virtex-6 FPGA XC6VLX130T, and use the pin mode to set the DAC to its default mode (SCLK, ADIO,CSB and SDO are all set to '0' while give a positive pulse with 0.2us width on RESET), and I notice that the DCO is set to high with no clock output on it, and there is no signals on IoutXP and IoutXN, can any one help me and give the possible reasons? Thanks.
