DESCRIPTION
The SN65LVDS047 is a quad differential linedriver
that implements the electrical characteristics of
low-voltage differential signaling (LVDS). This
signaling technique lowers the output voltage levels
of 5-V differential standard levels (such as
EIA/TIA-422B) to reduce the power, increase the
switching speeds, and allow operation with a 3.3-V
supply rail. Any of the four current-mode drivers will
deliver a minimum differential output voltage
magnitude of 247 mV into a 100-Ω load when
enabled.
The intended application of this device and signaling
technique is for point-to-point and multi-drop
baseband data transmission over controlled
impedance media of approximately 100 Ω. The
transmission media may be printed-circuit board
traces, backplanes, or cables. The ultimate rate and
distance of data transfer is dependent upon the
attenuation characteristics of the media, the noise
coupling to the environment, and other system
characteristics.
The SN65LVDS047 is characterized for operation
from -40°C to 85°C.
