Apparatus and methods are disclosed, such as those involving deskewing serial data transmissions. One such apparatus includes a plurality of receivers, each of which is configured to receive a serial data stream. Each of the receivers includes a shift register including a plurality of stages arranged in sequence to propagate a stream of characters. Each of the stages is configured to store a character, and shift the character to a next stage in response to a clock signal. The receiver also includes a multiplexer having a plurality of inputs, each of the inputs being electrically coupled to a respective one of the stages of the shift register, and to select one of the stages to generate an output such that the outputs of the multiplexers in the receivers are deskewed.

This application is related to APPARATUS AND METHOD FOR DESKEWING SERIAL DATA TRANSMISSIONS (Ser. No. 13/044,432, filed on even date herewith), the disclosure of which is incorporated by reference in its entirety herein.
1. Field
Embodiments of the invention relate to electronic devices, and more particularly, in one or more embodiments, to serial data transmission for electronic devices.
FIG. 1 is a schematic block diagram illustrating an example electronic system including two devices connected via multiple serial lanes.
FIG. 2 is a schematic block diagram illustrating another example electronic system including two transmitter devices and one receiver device connected via two links, each of which includes multiple serial lanes.
FIG. 3 is a schematic block diagram illustrating a transmitter and a receiver connected via a serial lane according to one embodiment.
The following detailed description of certain embodiments presents various descriptions of specific embodiments of the invention. However, the invention can be embodied in a multitude of different ways as defined and covered by the claims. In this description, reference is made to the drawings where like reference numerals indicate identical or functionally similar elements.
Overview of Electronic Systems Having Serial Links
Referring to FIG. 1, an electronic system for transmitting data via a serial link according to one embodiment will be described below. The illustrated system 100 includes a first device 110, a second device 120, a serial link 130 including a plurality of serial lanes 130a-130n, and a frame clock generator 150. The term “link” refers to a data communication path between two devices, and a link can include one or more lanes, each of which provides electrical connection between a transmitter and a receiver in the two devices.
