UCC2946: WDO stability

Part Number: UCC2946

Hi, is the WDO output reccommended to have attached a decoupling capacitor for filtering the signal? In my application, this signal is connected to the RESET input of a flip flop, which is sometimes suddenly triggered for no apparent reason (Remaining WDI toggled and WDO at a constant high level). I was wondering if WDO was not clean enough and could show peaks or some kind of noise causing the flip flop to trigger due to an instantaneous detected low level.
