What is PLL jitter transfer for adsp21489?  Can I use spread spectrum clock generator?

We're planning a new board using the ADSP21489 and because of its 3.3V singled-ended SDRAM interface we want to have every EMI mitigation factor possible designed into the board.  I'm having trouble finding any detailed information on the main PLL (taking CLKIN as an input) as to the PLL loop bandwidth, jitter transfer function etc.  Mainly I want to be sure that a standard spread spectrum clock generator with fmod=33kHz will work with this part.
