Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022088984
Kind Code:
A
Abstract:
To provide a control device that can suppress the occurrence of signal waveform distortion within a threshold voltage range while enabling hot-swap.SOLUTION: A motherboard is formed with a main wiring 2 including a plurality of differential transmission lines 21 for transmitting a differential signal. A terminating resistor 22 is provided at both ends of each of the plurality of differential transmission lines 21, and connects the plurality of differential transmission lines 21 to each other. A plurality of daughter boards 4 are connected in parallel to each other via the main wiring 2. The line characteristic impedance Zdiff of each differential transmission line 21 is larger than a terminating resistance value Rterm which is the resistance value of the terminating resistor 22.SELECTED DRAWING: Figure 2
