RECEIVER FUNCTION TABLE
The SN65LVDS1050 is similar to the
SN65LVDS050 except that it is characterized for
operation with a lower supply voltage range and
packaged in the thin shrink outline package for
portable battery-powered applications.

The differential line drivers and receivers use
low-voltage differential signaling (LVDS) to
achieve signaling rates as high as 400 Mbps. The
drivers provide a minimum differential output
voltage magnitude of 247 mV into a 100-Ω load
and receipt of 100-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 SN65LVDS1050 is characterized for operation from –40°C to 85°C.
