description

The SN65LVDM179, SN65LVDM180,
SN65L VDM050, and SN65LVDM051 are differen­tial line drivers and receivers that use low-voltage
differential signaling (LVDS) to achieve signaling
rates as high as 400 Mbps. These circuits are
similar to TIA/EIA-644 standard compliant
devices (SN65LVDS) counterparts, except that
the output current of the drivers is doubled. This
modification provides a minimum differential
output voltage magnitude of 247 mV into a 50-Ω
load and allows double-terminated lines and
half-duplex operation. The receivers detect a
voltage difference of 100 mV with up to 1 V of
ground potential difference between a transmitter
and receiver.

The intended application of these devices and
signaling technique is half-duplex or multiplex
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 SN65LVDM179, SN65LVDM180, SN65LVDM050, and SN65LVDM051 are characterized for operation
from –40°C to 85°C.
