SN65DSI84-Q1: SN65DSI84-Q1 PLL UNLOCK issue

Hi，We use sn65dsi84-q1 to driving a  LVDS panel  (1920*1080),  the soc is Qualcomm 820A,   sn65dsi84-q1 use  DSI clock as reference clock,    and we find  a small part of the system（about 0.5%) will report  PLL UNLOCK,    when reset(set enable pin to low) the sn65dsi84-q1,   the mistake is  still being,   after few minutes later, the pllunlock is  disappear  。 I don't know what cause  PLL UNLOCK mistake, and how to recover from  error  ？ is the  DSI CLOCK jitter cause pllunlock ?
