	LVDS Bus Interface Description
		LVDS may be used with either a cable or board [PWB] interface [bus], and may be referenced by other specifications as their Electrical interfaces.
		LVDS is designed with an output voltage swing of 350mV with speeds at better then 400Mbps into a 100 ohm load, across a distance of about 10 meters.
		LVDS is a scalable bus; one uni-directional link or multiple links may be used.

	The secrets of successful communications using LVDS - 10/13/2005 - EDN
		LVDS targets use in 100Ω environments and thus is unsuitable for loads greater than those that the TIA/EIA-644A standard specifies.
		LVDS receivers accept an input of 0 to 2.4V, which means that the receiver can have a ground shift that can be approximately 1V.
		LVDS is an appropriate technology for point-to-point- and multipoint-system technologies.

	LVDS Splitter Simplifies High-Speed Signal Distribution - Maxim/Dallas
		LVDS is seeing increased use in high-speed systems where signal integrity, low-jitter (jitter can be defined as the deviation in a signal's output transitions from their ideal positions in time) and good common-mode performance are required.
		Many of the advantages of LVDS are due to its differential nature: it is immune to common-mode noise and, in theory, emits no noise itself (this assumes completely symmetrical differential signals - i.e., no skew between the positive and negative outputs).
		Since LVDS is differential, the magnitude of current spikes drawn from its power supplies is lower and can be handled easier with suitably placed decoupling capacitors of reasonable value.

	Low voltage differential signaling - Wikipedia, the free encyclopedia
		LVDS is a differential signaling system, which means that it transmits two different voltages which are compared at the receiver.
		LVDS is often used for serial data transmission, which involves sending data bit-by-bit down a single wire (as opposed to parallel transmission, in which several bits, usually in multiples of eight, are sent down many wires at once).
		The present form of LVDS was preceded by an earlier attempt, SCI-LVD, which was a subset of the Scalable Coherent Interconnect (SCI) specified in the IEEE 1596.3 standard.

	CommsDesign - Secrets Revealed: Creating accurate LVDS IBIS models (Site not responding. Last check: 2007-10-26)
		LVDS (Low Voltage Differential Signaling) is emerging as the serial I/O technology of choice in communications systems because they offer the advantage of very high speed--up to 40 Gbit/s--with reduction in bus width and power.
		For example, when the non-inverting output of a LVDS device has an output voltage of 1.5V, then through compensation by internal circuitry of the device the voltage at the inverting output will attempt to reach 1.0V such that the sum of voltages between the outputs is equal to 2V(OS).
		In this case, data is being gained for the non-inverting output of the LVDS device, so a dependent voltage source should be put on the output of the inverting output such that a constant voltage equal to 2V(OS) can be maintained between the inverting and non-inverting outputs during the DC voltage sweep.

		LVDS is a physical layer data interface standard defined by the TIA/EIA-644 and the IEEE 1596.3 standards.
		Like other differential signaling standards, LVDS radiates less noise than single-ended signals due to the canceling of magnetic fields, and is more immune to noise because it is coupled onto the two wires as a common-mode signal (i.e., equal levels of noise appear on both lines).
		An LVDS serializer, used in combination with a deserializer (not shown), eliminates the wide data buses and associated large, expensive backplanes required when standard TTL signaling is used.

		LVDS signals are differential signal technologies with a swing of 250 to 400mV and a DC offset of 1.2V.

	Interfacing to LVDS with the NI 655X Digital Waveform Generator/Analyzer- Developer Zone - National Instruments
		The LVDS specification allows for an input voltage range from 0 to 2.4V, so a wide range of acceptable values are available.

		Depending on the LVDS device that you use, some current may be drawn through the negative leg of the signal, so the resulting voltage on channel 1 will be less than 1.2 V. The driver also inverts the signal, causing channel 0 to see the lower voltage (figure 8).
