Phase splitter using digital delay locked loops

Phase splitter using digital delay locked loops

A phase splitter uses digital delay locked loop (DLL) to receive complementary input clock signals to generate a plurality of output signals having different phase shifts. When the DLL is locked, the delay resolution of the phase splitter is equal to two delay stages of the DLL.
