BoltGATE 20-25 User Manual Rev. 1-1 6 Front Side Overview
6.6.3.3 MVB ESD+ Connection Notes
An ESD segment shall be terminated electrically at each end by a terminator.
The terminator shall present an impedance of 120,0 Ω ± 2 % measured at 1,0 BR.
Example of terminator (from the IEC 61375-1: 2007):
The terminator shown in the following figure presents an impedance of 120,5 Ω and biases the line with
about 0,786 V. Note that the Vpp source shall have a very low inner impedance in the frequency range of
0,5 BT until 2 BT in order that the equivalent terminator impedance seen by the line is within the specified
tolerance. Resistors are belonging from the E96 series 1% tolerance.
Components Type Value Connections Type Value
Ru Resistor 383 Ω Vpp Supply voltage 5,0 V
Rm Resistor 143 Ω GND Reference voltage 0,0 V
Rd Resistor 383 Ω
Figure 6.3 - Example of terminator
The terminator shall be included into a connector, to be plugged into the empty receptacle of a device
located at the end of the segment, according to the wiring shown in the following figure:
