The SN65LVDM176D is a half-duplex LVDM Transceiver uses low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbit/s. The 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 247mV into a 50R load and allows double-terminated lines and half-duplex operation. The receivers detect a voltage difference of less than 50mV with up to 1V 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 100R characteristic impedance. The transmission media may be printed-circuit board traces, backplanes or cables.
