are made per second expressed in the units bps (bits per
second).
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 Ω 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 Ω. 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.
