Talk:Low-voltage differential signaling

LVDS vs DS

I think the first section, which describes differential signaling in general, should be farmed out to a separate article on differential signaling, which can be referred to from here, RS-485, from USB, and probably from tons more places too. I'll do this in a couple of days, unless someone objects. - John Fader Dec 9, 2004

Urgh, and there's probably some merging to be done with balanced line. I'm afraid this analogy stuff is getting rather too far from my core area of expertise for me to do a terribly good job. Help! - John Fader Dec 9, 2004

I do not believe they should be merged. Differential Signaling is a concept, the idea of sending a signal on a pair of differential wires. LVDS is a standard (http://www.iec.org/online/tutorials/low_voltage/). While the current article does not go in depth, future authors could potentially expand it into covering the basic definion of LVDS timings and such, as well as all of their derivates (such as Infiniband... memory serves me its not QUITE LVDS). Combining the articles could stifle authorship for fear of making the article deviate too greatly from the broad concept of Differential Signaling. Maybe when my work load lightens up, I'll expand it myself. - Cort Ammon May 3, 2006

No merge. As above, one is a concept, another is an implementation. -- RevRagnarok ^{Talk Contrib Reverts} 16:28, 26 June 2006 (UTC)

I agree with John Fader that we *should* have separate articles on each of the many specific implementations -- LVDS, RS-485, USB, etc. -- and *also* have an article on the general concept of differential signaling. I agree that we don't need to repeat a chapter of information on the general concept of "differential signaling" in each and every Wikipedia article on the dozens of specific implementations that use differential signaling.

Something seems to have gone terribly wrong with these two sentences. I don't even know what is meant, perhaps someone can help :

Without a load resistor the whole wire has to be loaded and unloaded for every bit of data. Using high frequencies and a load resistor so that a single bit only covers a part of the wire (while traveling near light speed) is more power efficient.

Just take it out; or ask whoever added it to explain. If someone has a good point, they can put it back with a source. Dicklyon (talk) 17:46, 1 July 2009 (UTC)

The end?

from http://www.technewsworld.com/story/VGA-Given-5-Years-to-Live-71420.html :

"Both Intel and AMD will also stop supporting low-voltage differential signaling (LVDS) by 2013. LVDS is an electrical signaling system that enables high transmission rates over twisted-pair cables. It moves video data from graphics adapters to computer monitors. Apple's (Nasdaq: AAPL) FireWire serial bus interface uses LVDS."

Incomplete sentence: "High speed video link." under Standards

I am not sure if that should be joined to the previous sentence as an example, taken out, modified into a proper sentence, or given a link to a standard. — Preceding unsigned comment added by Frostybeard (talk • contribs) 14:12, 7 February 2018 (UTC)

The whole standards section appears to have missing words, I'm not an expert on this but it looks like it needs to be edited by someone who knows the topic BPsailor (talk) 21:15, 24 November 2020 (UTC)

"LVDS" is not a flat panel interface and did not "get replaced by DisplayPort"

"Intel and AMD published a press release in December 2010 stating they would no longer support the LVDS LCD-panel interface in their product lines by 2013. They are promoting Embedded DisplayPort and Internal DisplayPort as their preferred solution. However, the LVDS LCD-panel interface has proven to be the lowest cost method for moving streaming video from a video processing unit to a LCD-panel timing controller within a TV or notebook, and in February 2018 LCD TV and notebook manufacturers continue to introduce new products using the LVDS interface."

(Embedded) DisplayPort did not replace "LVDS". In fact, DisplayPort uses LVDS as its physical layer. (Embedded) DisplayPort may have replaced FPD-Link. Both DisplayPort and FPD-Link make use of LVDS as their physical layer, as do S-ATA and PCI-Express and even HyperTransport. As a physical layer protocol, LVDS only determines voltage levels and impedances used, but says nothing about the number of differential pairs used or the clock rates with which they are driven, whether there is a separate clock signal or "clock recovery" from the data is used, and of course what data is transmitted over the link and in which format it is or what application it is used for. FPD-Link may have been replaced, but LVDS is ubiquitous. 88.130.219.83 (talk) 00:52, 19 January 2021 (UTC)
