3 Description
The SN65LVDS049 device is a dual flow-through
differential line driver-receiver pair that uses low- voltage differential signaling (LVDS) to achieve
signaling rates as high as 400 Mbps. The driver and
receiver electrical interfaces are compliant to the
TIA/EIA-644-A standard.
The intended application of this device and signaling
technique is for point-to-point baseband data
transmission over controlled impedance media of approximately 100-Ω characteristic impedance. 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 application
specific characteristics.
The SN65LVDS049 is characterized for operation
from –40°C to 85°C
