DATA STROBE MULTIPLEXER

The invention relates to a data strobe multiplexer. Devices and techniques are disclosed herein for determining, using a host device, a timing relationship between a data strobe signal, such as from an embedded eMMC device, and an internal clock signal. The host device can control a delay circuit using the determined timing relationship, such as to align received read data for sampling, or to determine or adjust a delay value of the delay circuit. 本发明涉及一种数据选通多路复用器。在本文中揭示用于使用主机装置来确定例如来自嵌入式多媒体卡eMMC装置的数据选通信号与内部时钟信号之间的时序关系的装置及技术。所述主机装置可使用所述所确定时序关系来控制延迟电路，以便对准所接收读取数据以用于取样，或者确定或调整所述延迟电路的延迟值。
