The SN65MLVD047A is a quadruple line driver that complies with the TIA/EIA-899 standard, Electrical Characteristics of Multipoint-Low-Voltage Differential Signaling (M-LVDS). The output current of this M-LVDS device has been increased, in comparison to standard LVDS compliant devices, in order to support doubly terminated transmission lines and heavily loaded backplane bus applications. Backplane applications generally require impedance matching termination resistors at both ends of the bus. The effective impedance of a doubly terminated bus can be as low as 30 . The SN65MLVD047A devices allow for multiple drivers to be present on a single bus. SN65MLVD047A drivers are high impedance when disabled or unpowered. Driver edge rate control is incorporated to support operation.
