Application Design of ADPLL Based on Editable Logic Device

The traditional analog phase-locked loop (APLL) has a short lock time, which can ensure the steady-state phase difference between the reference clock source and the output clock. However, its center frequency is limited by the VCO, and the range is small, and the loop bandwidth is wide; when the reference source is interrupted or the […]

Next generation software defined transceivers that offer significant frequency hopping (FH) advantages

abstract This paper deeply discusses the concept of frequency hopping (FH) and how to realize the four frequency hopping characteristics by flexibly designing the phase-locked loop (PLL) architecture of adrv9002sdr transceiver. These features can provide users with powerful frequency hopping functions, enabling them to handle applications such as link 16 and fast real-time carrier frequency […]

Anti islanding and smart grid protection

Anti islanding protection is very important to ensure that the grid connected energy collection system cuts off the connection with the grid when the grid itself is powered off. However, identifying power losses in the grid can be challenging and requires a method that can find an appropriate balance between sensitivity to normal fluctuations in […]
