Abstract:
Apparatuses and methods for determining a phase relationship between an input clock signal and a multiphase clock signal are disclosed. An example apparatus includes a clock path configured to receive a clock signal and provide internal clock signals and a command path configured to receive a command and propagate the command through the command path responsive to the internal clock signals and provide an internal command having a timing that reflects a timing of the clock signal. The example apparatus further includes a data clock path configured to receive a data clock signal and provide multiphase clock signals based on the data clock signal and provide a delayed multiphase clock signal, and further includes a clock synchronization circuit configured to receive the delayed multiphase clock signal and latch a logic level of the delayed multiphase clock signal responsive to the internal command.
