The SN65LVDS180, SN65LVDS050, and SN65LVDS051 are differential line drivers and receivers
that use low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbps.
The TIA/EIA-644 standard compliant electrical interface provides a minimum differential output
voltage magnitude of 247 mV into a 100-Ω load and receipt of 50-mV signals with up to 1 V of ground
potential difference between a transmitter and receiver.
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.
(Note: 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 devices offer various driver, receiver, and enabling combinations in industry
standard footprints. Since these devices are intended for use in simplex or distributed simplex bus
structures, the driver enable function does not put the differential outputs into a high-impedance
state but rather disconnects the input and reduces the quiescent power used by the device. (For
these functions with a high-impedance driver output, see the SN65LVDM series of devices.) All
devices are characterized for operation from −40°C to 85°C.
