Impedance Matching: Use matching networks (resistors, capacitors, inductors) to match the impedance of the source and load, minimizing reflections and impedance discontinuities. Transmission line impedancealso depends on the arrangement of nearby lines. Parasitic capacitance from the PCB substrate a...
We refer to its PCI-e demo board, howver, we found that the traces don't have AC coupling capacitors of XCVR (RX&TX) between FPGA and SFP. Do we need to add AC coupling capacitor for our board when we use fpga interconnecting with SFP? Translate...
In cell stimulation, electrical energy can be transferred to the culture medium by conductive, capacitive or inductive coupling2. In the first case, two parallel metal electrodes are placed in direct contact with the culture medium, hence the term direct coupled (DCoupled) to describe this procedu...
Power cord wire colors are sometimes non-standard so use a multimeter to identify Hot and Neutral. Europeans sometimes use the letters E: Earth (safety ground), L: Line (hot) and N: Neutral to describe the three plug wires. The 325 volts AC power from the power transformer is fed ...
·Implement termination techniques like parallel termination (e.g., resistors) to minimize signal reflections. ·Use A.C. coupling capacitors for D.C. isolation in certain applications. 4.Grounding Strategies: ·Ensure solid ground planes, minimizing ground loop and noise. ...
This allows the mixer output and the ADC input to be connected directly. The absence of AC-coupling capacitors ensures that there are no charging/discharging transients when the mixer output switches abruptly (for example, during a frequency step at the input of the mixer). The use ...
Identify the source The first step in securing your equipment is locating the EMI source. There are various methods for doing this. First, measure the distance to theantennaand the level of interference generated. It could be necessary to redesign the circuit board if the signal is too strong...
Identify and reduce current loops Request PCB Manufacturing & Assembly Quote PCB design One needs to consider the board format from the beginning phases of PCB improvement. A significant standard that applies to any high-power PCB is to decide the way followed by the power. The amount and locat...
Capacitors C1 and C2 can be seen having the values of 470 pF each in this pierce circuit design. With these values the circuit must oscillate without any problems within a extensive range of frequencies. If the frequency is just a few MHz then you may want to decrease the value of C1 an...
While the lock indications are required to identify the beginning of proper data reception, for any link failures or data corruption, the best indication is the contents of the error counter in the BIST_ERR_COUNT register 0x57 for each RX port. 3.2.2 BIST Procedure 953 and 954 Digital ...
