Abstract:
The present invention is directed to data communication. More specifically, embodiments of the present invention provide a method for acquiring sampling frequency by sweeping through a predetermined frequency range, performing data sampling at different frequencies within the predetermined frequency range, and determining a target frequency for sampling data based on a maximum early peak frequency and a maximum late peak frequency. There are other embodiments as well.
Abstract:
The present invention is directed to data communication systems and methods. In various embodiments, the present invention provides a CML device that changes output frequency response by varying resistance values of its load resistance and source resistance. A bias control voltage is used to adjust the tail current of the CML device, and the tail current adjusts the output gain of the CML device. There are other embodiments as well.
Abstract:
The present invention is directed to integrated circuits. In a specific embodiment, high frequency signals from an equalizer are directly connected to a first pair of inputs of a sense amplifier. The sense amplifier also has a second pair of inputs, which can be selectively coupled to output signals from a DAC or high frequency loopback signals. There are other embodiments as well.
