RSDS/LVDS Driving Circuits Suitable for Low Working Voltages

摘要

A driving circuit includes a first switchable current module for providing a first current, a second switchable current module for providing a second current, a first switchable current source having an input end coupled to a first output end of the second switchable current module, a second switchable current source having an input end coupled to a second output end of the second switchable current module, a third switchable current source having an input coupled to a first output end of the first switchable current module, a fourth switchable current source having an input end coupled to a second output end of the first switchable current module, and a termination impedance circuit. The termination impedance circuit has a first end coupled to the first switchable current source and the third switchable current source, and a second end coupled to the second switchable current source and the fourth switchable current source.
