SN65MLVD047

SLLS606A – MARCH 2004 – REVISED JULY 2005

MULTIPOINT-LVDS QUAD DIFFERENTIAL LINE DRIVER

•

Differential Line Drivers for 30-

Ω to 55-Ω

The SN65MLVD047 is a quadruple line driver. The

output current of this device has been increased, in

Clock Frequencies up to 100 MHz

comparison to standard LVDS compliant devices, in

order to support doubly terminated transmission lines

•

Supports Multipoint Bus Architectures

and heavily loaded backplane bus applications.

•

Operates from a Single 3.3-V Supply

Backplane applications generally require impedance

•

Characterized for Operation from –40

°C to

matching termination resistors at both ends of the

85

°C

bus. The effective impedance of a doubly terminated

bus can be as low as 30

Ω due to the bus

The data rate of a line is the number of voltage transitions that

are made per second expressed in the units bps (bits per

second).
