ABSTRACT:
A CMOS differential twisted-pair driver which utilizes CMOS switches and current sources advantageously. No alternative power supply is required, the switches do not have to be low impedance and the device is low power. The preferred embodiment driver further limits signal overshoot and common mode energy. The signal transmission facility is bi-directional so an off state is provided. It is doubly terminated to provide for symmetry, improved bandwidth and reduces reflective signal noise. The double termination also provides for faster rise and fall times which reduces the systems sensitivity to receiver offset.
