Line 45: ==Physical Layer (L1)== ===D-PHY=== Versions 1.0 and 1.1 of UniPro use MIPI's D-PHY technology for the off-chip Physical Layer. This PHY allows inter-chip communication over printed circuit board traces as well over roughly 20 cm of cabling. Data rates of the D-PHY are variable, but are in the order of 500-1000 Mbit/s (~~although~~ lower speeds are supported, but at decreased power efficiency). The D-PHY was named after the Roman number for 500 ("D"). The [[D-PHY]]<ref>[https://members.mipi.org/mipi-adopters/file/Specifications/Board%20Approved/MIPI%20D-PHY%20Specification_v00-90-00_final_11152007132023.pdf MIPI D-PHY 0.90 specification],requires an account at the MIPI website</ref> uses differential signaling to convey PHY symbols over micro-stripline wiring. A second differential signal is used to transmit the associated clock signal from the source to the destination. The D-PHY technology thus uses a total of 4 signal wires per direction. Traffic and return traffic are totally independent at this protocol level.
