Description

Technical field [0001] The invention relates to an LVDS cable for automotive wires. Background technique [0002] LVDS cable is (Low-Voltage Differential Signaling) low-voltage differential signal cable. It is a signal transmission mode proposed by National Semiconductor Corporation in 1994. It is a level standard. LVDS stands for low-voltage differential signal transmission. New technology for high-performance data transmission applications. Because it can make the system supply voltage as low as 2V, it can also meet the needs of future applications. This technology is based on the ANSI / TIA / EIA-644LVDS interface standard. LVDS technology has 330mV low voltage differential signal (250mVMIN and450mVMAX) and fast transition time. This allows products to reach high data rates from 100Mbps to more than 1Gbps. In addition, this low-voltage swing can reduce power dissipation and has the advantages of differential transmission. LVDS technology is used for simple line driver and rec...
