Web25 Mar 2014 · If you want to send data at an average rate of 100 kb/s, you would set the clock speed higher -- anywhere from 110 to 150 kHz depending on the message length. Note that some I2C devices can't handle more than 100 kHz (although they are becoming rarer), so you could never achieve 100 kb/s. – tcrosley Mar 24, 2014 at 9:21 WebThe PCA9518 is an expandable five-channel bidirectional buffer for I 2 C and SMBus applications. The I 2 C protocol requires a maximum bus capacitance of 400 pF, which is derived from the number of devices on the I 2 C bus and the bus length. The PCA9518 overcomes this restriction by separating and buffering the I 2 C data (SDA) and clock …
