Basic LVDS circuit. FPD-Link was the first large-scale application of the low-voltage differential signaling (LVDS) standard. National Semiconductor immediately provided interoperability specifications for the FPD-Link technology in order to promote it as a free and open standard, and thus other IC suppliers were able to copy it.
CML is the physical layer used in DVI, HDMI and FPD-Link III video links, the interfaces between a display controller and a monitor. [ 2 ] In addition, CML has been widely used in high-speed integrated systems, such as for serial data transceivers and frequency synthesizers in telecommunication systems.
The original FPD-Link designed for 18-bit RGB video has 3 parallel data pairs and a clock pair, so this is a parallel communication scheme. However, each of the 3 pairs transfers 7 serialized bits during each clock cycle. So the FPD-Link parallel pairs are carrying serialized data, but use a parallel clock to recover and synchronize the data.
OpenLDI is based on the FPD-Link specification, which was the de facto standard for transferring graphics and video data through notebook computer hinges since the late 1990s. Both OpenLDI and FPD-Link use low-voltage differential signaling (LVDS) as the physical layer signaling, and the three terms have mistakenly been used synonymously. (FPD ...
Furthermore, since FPD-Link mainly uses electrical digital signaling between zero volts (the ground level) and 1.2 volts based on its standard, it became a significant constraint of designing higher density LSIs. Under such circumstances, many substitutable interfaces such as DVI, HDMI, DisplayPort, and V-by-One HS are offered and adopted widely.
Single-link DVI-D male plug. Dual-link DVI-D male plug. Digital Visual Interface (DVI). Five variants are: DVI-I single link, DVI-I dual link, DVI-D single link, DVI-D dual link, and DVI-A. Male Mini-DVI plug on top of a 12-inch PowerBook G4; female port is second from left. Mini-DVI: VGA, DVI, television. Apple Computer alternative to Mini-VGA.
The link architecture is based on DVI, using exactly the same video transmission format but sending audio and other auxiliary data during the blanking intervals of the video stream. HDMI 1.0 allows a maximum TMDS clock of 165 MHz (4.95 Gbit/s bandwidth per link), the same as DVI. It defines two connectors called type A and type B, with pinouts ...
Internal DisplayPort (iDP) is a standard that defines an internal link between a digital TV system on a chip controller and the display panel's timing controller. Version 1.0 was approved in April 2010. It aims to replace currently used internal FPD-Link lanes with a DisplayPort connection.
