description
The SN65LVDM176 is a differential line driver and receiver configured as a transceiver that uses low-voltage
differential signaling (LVDS) to achieve signaling rates as high as 400 Mbit/s. 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 50Ω
load and allows double-terminated lines and half-duplex operation. The receivers detect a voltage difference
of less than 100 mV 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 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. (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 SN65LVDM176 is characterized for operation from –40°C to 85°C.
