摘要:
A dual mode digital interface supports the HyperTransport Standard and at least one other interface standard. The dual mode digital interface includes a plurality of data line deskew/sampling blocks, a data group deskew module, and an enablement control module. The plurality of data line deskew/sampling blocks deskew and sample incoming data on respective data lines based upon a clock signal to produce deskewed data. The data group deskew module receives deskewed data from each of the plurality of data line deskew/sampling blocks and removes inter-data line skew from the deskewed data to produce received data. The plurality of data line deskew/sampling blocks and the data group deskew module can be configured in a first mode when supporting an aspect of the HyperTransport Standard and configured in a second mode when supporting the at least one other interface standard. In the alternative, a plurality of data line deskew/sampling blocks and the data group deskew module may be set based upon a training sequence received from a link partner.
