Impact of adjusting the clock frequency based on Encoder-Decoder Bus System

Abstract

This paper presents the impact of adjusting the clock frequency on our bus called Encoder-Decoder Bus System. The integrated circuits for encoder and decoder (MC145026/MC145027) are used to implement our bus system based on Arduino Uno R3 microcontroller. We consider that the clock frequency of encoder and decoder may affect to the data transfer rate between the source and destination nodes. We select the clock frequency of 8.53 KHz, 42.6 KHz, 100 KHz, 181 KHz and 400 KHz for synchronizing between the encoder and decoder. As the results, we found that our bus system can provide the increasing of data transfer rate approximately 172 bps, 1,270 bps, 3,178 bps, 6,232 bps and 10,908 bps, respectively which can support the maximum of node equal 35 nodes at the transmission range of 2.5 kilometers.
