摘要:
An apparatus for transmitting signals over a signal line includes a transmitter with an output connectable to the signal line, for a synchronization signal in a power saving mode and a wanted signal in a normal mode of operation, wherein the synchronization signal has a reduced amplitude as compared to an amplitude of the wanted signal and has a periodic data pattern so that the synchronization signal permits maintaining an alignment of the synchronization signal and a reference signal in the receiver.

The present invention refers to a memory system with a controller and a memory device with a communication channel with a data path and a timing path coupling the controller with the memory device. The communication channel has different propagation times for the data path and the timing path exchanging a information signal and a timing signal between the controller and the memory device. The timing signals are used for determining the value of the information signal, and a retiming circuit that is connected with the communication channel compensates, depending on a compensation signal on an input, the delay between the data path and the timing path for exchanging a information signal and a timing signal between the controller and the memory device.

Disclosed herein are systems and methods for fast phase alignment and clock and data recovery. Systems and methods may include a fast phase alignment component configured to generate a selected phase signal based on a characteristic of an incoming signal. A clock and data recovery component may also be configured to receive the selected phase signal and perform a clock and data recovery function on the incoming signal using the selected phase signal.

An arrangement for generating a transmission clock signal and a reception clock signal is proposed in which only a single voltage-controlled oscillator is used, the reception clock signal being generated by phase-adjusting means whereas the transmission clock signal is generated directly by the voltage-controlled oscillator. Cross-talk between a plurality of voltage-controlled oscillators can be prevented in this way. Also, various measures are proposed for optimizing a circuit of this kind.
