A digital-to-charge converter, a digital-to-analog converter, and a method of operating a digital-to-charge converter are provided. An illustrative method of operating a digital-to-charge converter is provided that includes: receiving a digital input signal at the digital to charge converter, charging one or more capacitors during a pre-evaluation period, where the one or more capacitors are charged with a supply voltage based the digital input signal, disconnecting the one or more capacitors from the supply voltage during an evaluation period, and generating an analog output signal from the digital to charge converter based on an evaluation of charge of the one or more capacitors during the evaluation period.

High speed charge mode digital-to-analog converter

A transmitter including a digital-to-analog converter (DAC) to generate an analog output corresponding to a transmitted signal. The transmitter further includes an analog-to-digital converter (ADC) coupled to the DAC. The ADC measures the analog output of the DAC to identify a set of digital samples. The ADC identifies, from the set of digital samples, a set of valid samples, wherein each valid sample has a voltage within a voltage range. The ADC extracts one or more signal properties from the set of valid samples.

Apparatuses and associated methods are described that provide networking connections that reduce cross-talk and other interference in communications systems. The network connection includes a printed circuit board (PCB) that defines a first end, a second end, and a grounding region on a surface of the PCB proximate the first end. The network connection includes network connectors proximate the first end, soldering pad pairs proximate the second end, and electrical traces therebetween. At least a first soldering pad pair is offset from a second soldering pad pair with respect to an edge of the PCB at the second end, such that, in an operational configuration in which at least the first soldering pad pair and the second soldering pad pair receive a differential signal cable, each differential signal cable is supported by the PCB in a corresponding offset configuration thereby reducing cross-talk between the differential signal cables.

Apparatuses and methods for improved network connections

An optimized ground (GND) network connection is provided between a Quad Small Form-factor Pluggable (QSFP) connector and a printed circuit board (PCB). The optimized GND network creates a 'GND Island' around the signal pads by adding GND cage around the signal pads (at the empty corridor and in front of QSFP pads) and GND TH (ground through hole) vias from both sides of signal pads (at the empty corridor and in front of QSFP pads).
