Current LVDS parts operate from DC to Giga bits per second range. A. LVDS is a short haul interface envisioned to drive interconnects of a few inches to 10's of meters. Once again this is application specific depending upon the LVDS device employed and the required signal quality. Power dissipation is minimized in a number of ways. This includes the CMOS process, the current mode driver design, and also the small load current.
Noise generation is minimized in a number of ways.
The signal swing is only 300mV, and also a true balanced differential data transmission scheme, and the current mode driver all limit noise generation. A. YES, for two reasons. Since the drivers are current mode, the resistor is required to complete the current loop. Also, since LVDS features sub-nanosecond transition times, the interconnect will be a transmission line, and a termination is required to limit reflections. Always use a balanced media and closely-coupled traces to obtain the maximum common mode rejection.
