1.5 Single ended (line) impedance, Differential impedance
Definition of Characteristic Impedance
At a certain frequency, relative to a reference layer, the resistance of its high-frequency signals or electromagnetic waves in the process of transmission is called the characteristic impedance, which is the vector summation of electrical impedance, inductive reactance, capacitance resistance.
The classification of characteristic impedance
Common characteristic impedance is divided into: (1) Single ended (line) impedance; (2) Differential impedance and (3) coplanar impedance, etc.
Single ended impedance refers to the measured impedance of a single signal line. Differential impedance refers to the impedance measured between the two transmission lines with equivalent width and spacing in differential drive. Coplanar impedance refers to the impedance measured when the signal line is transmitting between its surrounding GND / VCC (the space between the signal line to GND / VCC on both sides is equal).
The Determinant Condition Required for Impedance Control
When the signal is transmitted in the PCB conductor, if the length of conductor is close to the 1/7 of the signal wavelength, then the conductor at this time becomes a signal transmission line, the other general signal transmission lines are required to be done with impedance control. Whether it is required to control the impedance in PCB production is based on the customer's requirement, if the customer requires that a certain line width need to be done with impedance control, it is required to control the impedance of the line width in production.Three basic elements of impedance match are the output impedance (the original active parts), the characteristic impedance (signal line), the input impedance (passive parts) (PCB board)
