TMS320F28379D: Does the PLL module generate additional jitter?

Part Number: TMS320F28379D

Hi TI,

I am working on a project for ultral precision control of inverter. Since the current/voltage noise is quite sentive to the jitter of the PWM, I plan to use a very stable OCXO for the clock input of DSP. The selected OCXO is OH320-CC produced by connor winfield. The frequency stability of this OCXO is 1ppb and the phase jitter is 1ps rms. 

My question is: As the system clock is generated via the PLL module of this DSP, will the system clock be as stable as the OCXO? If not, is there any specification about the jitter of the clock system of this DSP?

Best regards!
