The magnetic field strength (magnitude) produced by a long straight current-carrying wire is found by experiment to be $B=\frac{{\mu}_{0}I}{2\pi r}\left(\text{long straight wire}\right)\\$, where I is the current, r is the shortest distance to the wire, and the constant ${\mu }_{0}=4\pi \times 10^{-7}\text{T}\cdot\text{ m/A}\\$ is the permeability of free space. electronic distance measuring equipment of accuracy 1:50,000 are also available. The octal members of the Fast Ethernet PHY family, the 88E3082 and 88E3083 devices, significantly lead the industry with the lowest power consumption (under. 1 degree of a 5712 MHz rf (50 fs timing accuracy). Additionally, since in CSMA/CD only a single device can transmit at a given time, there are practical limits to the number of devices that can coexist in a single network. The properties that Ethernet magnetics need to have are specified in the standard - for example, a transformer for a 100BASE-T connection is required to have an inductance value of. According to microcontroller - what is the difference between PHY and MAC chip - Electrical Engineering Stack Exchange, what a PHY chip does is basically DAC/ADC:. The reference voltage is determined by the requirements of the module's PHY and may be as low as 0V and as high as 3.
