    摘要: Techniques are described herein that provide an interface for receiving and deserializing digital bit stream(s). For instance, a receiver for a high-speed deserializer may include digital slicers, a digital phase interpolator, and a digital clock phase generator. The digital slicers may be configured to determine a digital value of a data input. The digital phase interpolator may be configured to generate an interpolated clock signal based on input clock signals that correspond to respective phases of a reference clock. The phase of the interpolated clock tracks the data input to the receiver through a clock recovery loop. The digital clock phase generator may be configured to generate output clock signals to control timing of the respective digital slicers. The receiver may further include a single digital eye monitor configured to monitor a data eye of the data input.

    摘要: A high-speed clock generator device includes a phase-interpolator (PI) circuit, a smoothing block, and inverter-based low-pass filters. The PI circuit receives a multiple clock signals with different phase angles and generates an output clock signal having a correct phase angle. The smoothing block smooths the clock signals with different phase angles and generates a number of smooth clock signals featuring improved linearity. The inverter-based low-pass filters filter harmonics of the clock signals with different phase angles.

    摘要: A high speed level shifter interfaces a high speed DAC to the digital information that the DAC processes. The level shifter may convert CMOS level digital representations to, for example, CML level digital representations for processing by the DAC. The level shifter conserves the voltage swing in the CMOS level representations (e.g., about 1V). The level shifter also avoids voltage overstress, using a feedback loop to constrain the voltage amplitude, and thereby facilitates the use of fast thin film transistors in its architecture.

    摘要: Methods and apparatuses are described for a DSP receiver with an analog-to-digital converter (ADC) having high speed, low BER performance with low power and area requirements. Speed is increased for multi-path ADC configurations by resolving a conventional bottleneck. ADC performance is improved by integrating calibration and error detection and correction, such as distributed offset calibration and redundant comparators. Power and area requirements are dramatically reduced by using low BER rectification to nearly halve the number of comparators in a conventional high speed, low BER flash ADC.
