DESCRIPTION
The SN65LVDM31 incorporates four differential line
drivers that implement the electrical characteristics of
low-voltage differential signaling. This product offers a
low-power alternative to 5-V PECL drivers with similar
signal levels. Any of the four current-mode drivers will
deliver a minimum differential output voltage
magnitude of 540 mV into a 100-Ω load when
enabled by either an active-low or active-high enable
input.
The intended application of this device and signaling
technique is for both point-to-point and multiplexed
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 and the noise
coupling to the environment.
The SN65LVDM31 is characterized for operation from
–40°C to 85°C.
