description
The SN65LVDM050, and SN65LVDM051 are differential line drivers and receivers that use low-voltage
differential signaling (LVDS) to achieve signaling rates as high as 500 Mbps (per TIA/EIA-644 definition). These
circuitsaresimilartoTIA/EIA-644standardcompliantdevices(SN65LVDS)counterparts, exceptthattheoutput
current of the drivers is doubled. This modification provides a minimum differential output voltage magnitude
of 247 mV across a 50-Ω load simulating two transmission lines in parallel. This allows having data buses with
more than one driver or with two line termination resistors. The receivers detect a voltage difference of 50 mV
with up to 1 V of ground potential difference between a transmitter and receiver.
The intended application of these devices and signaling techniques is point-to-point and multipoint, baseband
data transmission over a controlled impedance media of approximately 100 Ω of characteristic impedance. The
transmission media may be printed-circuit board traces, backplanes, or cables.
