The SN65LVDM179, SN65LVDM180, SN65LVDM050, and SN65LVDM051 are differenTIal line drivers and receivers that use low-voltage differenTIal signaling (LVDS) to achieve high signaling rates. 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 across a 50- 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 half duplex, baseband data transmission over a controlled impedance media of approximately 100 characteristic impedance.
