ADAU1361, PLL and Fs=32kHz

My MCLK=27MHz. I am need to get Fs=32kHz(frequency on pin LRCLK, p.43 Figure 57..59). That mean - it’s need PLL in fraction mode.


DataSheet state:

1. The PLL output clock rate is always 1024 × Fs (p.26).

2. The PLL outputs a clock in the range of 41 MHz to 54 MHz (p.27).

That is: Fs(min)=41MHz/1024=40kHz.


Is it impossible get Fs=32kHz?
