The Link45i has an advanced 1-Wire® front end based on extensive research with a variety of iButton® and 1-Wire® chip devices and network topologies. This presents controlled impedance to the bus, performs intelligent bus pre-charge, and has improved waveform timing.
Slew controlled drivers reduce EMI and ringing, while analog and digital filtering reduce noise sensitivity. A crystal-controlled time base eliminates the need for the driving software to be periodically recalibrated. It also assures consistent 1-Wire® waveform timing.
The Link45i will issue its own unique 16 digit 1-Wire® address to provide identification of the specific network, which is valuable when using multiple networks.
