Advantages of Closed-Loop Phase Locked Loop (PLL) - KBA82948
What are the advantages of phase-locked loop (PLL) in WirelessUSB-NL?
A closed-loop PLL eliminates the problem of frequency drift. This enables WirelessUSB-NL to transmit long payloads without repeatedly having to pay power penalties for relocking the PLL as in open-loop designs. This increases battery life of the product.
