Abstract

See full text

Semiconductor devices for synchronizing networks are described. A semiconductor device can include an analog phase-lock loop (APLL) configured to output a first signal. The semiconductor device can further include a first digital phase-lock loop (DPLL) configured to output a second signal. The semiconductor device can further include a second DPLL configured to output a third signal. A combination of the first signal and the second signal can be used to generate a first output clock signal. A difference resulting from a subtraction of the second signal from the third signal can be used to generate a second output clock signal.
