DESCRIPTION

The SN65MLVD047 is a quadruple line driver. The

output current of this 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 W due to the bus

terminations, as well as the capacitive load of bus

interface devices. SN65MLVD047 drivers allow for

operation with loads as low as 30 W. The

SN65MLVD047 devices allow for multiple drivers to

be present on a single bus. Driver edge rate control is

incorporated to support operation. The

SN65MLVD047 provides 9-kV ESD protection on all

bus pins.
