Stratix iv - PLL & loop filter characterisation information

HI

I need to create a system model in MATLAB.

In order to do so I need the transfer function of the low pass filter and the phase noise (or spectral density distribution) for the VCO in the associated with PLL's used in the EP4SE530H35C2.

Does anyone know if this information is readily available.

    i don't think its available. what kind of application do you need to simulate the PLLs at an analog level?

    thanks for the promt reply

    I am looking at jitter transfer on a high speed serial link

    as a function of the difference in transport delay between the common clock arriving at the transmit PLL and the Receive PLL.
