摘要： The present disclosure is generally directed to a method and apparatus to communicate data between two or more semiconductor devices. In an embodiment, a method includes synchronizing a master device with a slave device, where the master device includes a semiconductor device. Synchronizing includes transmitting a first synchronization marker data pattern via a first serial interface from the master device at a first time, and receiving a second synchronization marker data pattern via a second serial interface at the master device at a second time in response to transmitting the first synchronization marker data pattern. Synchronizing also includes determining, based at least in part on the first time and the second time, a third time when a reply is to be received by the master device in response to a request transmitted from the master device to the slave device.

摘要： The present disclosure is generally directed to a method of communicating data between two or more semiconductor devices. Serial interfaces using the method have a reduction in latency compared to conventional serial interfaces. The method enables features needed for a serial interface, such as limited run lengths and recognizable data boundaries to establish alignment. In addition, a method for synchronizing two or more semiconductor devices through serial interfaces has been presented. This is done by passing a marker data pattern through the system.

摘要： A Transmit line driver with selectable pre-emphasis and driver signal magnitudes comprises a primary current driver for setting a primary current level and a pre-emphasis current driver that provides an additional amount of current that is superimposed with or added to the primary current level produced by the primary current driver. The pre-emphasis current has either negative or positive magnitude based upon a pre-emphasis signal logic state. A first current selection module defines a reference signal that is used to select the primary current driver output signal magnitude in a first current mirror, while a second current selection module is used to define a second reference signal that selects a pre-emphasis current driver signal magnitude in a second current mirror. Logic generates a binary signal to both the first and second current selection modules to select the current levels as well as the pre-emphasis signal.
