Abstract: 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).

Abstract: An electronic circuit may include at least two capacitors arranged in parallel; at least two resistors arranged in series; a positive supply voltage connected to the resistors; a negative supply voltage connected to the resistors, the resistors producing a reference signal; a source circuit producing a source signal and connected to the positive supply voltage and negative supply voltage; and a receiving circuit connected to the positive supply voltage and negative supply voltage, and receiving the source signal and reference signal.
