SN65LVDM050

The SN65LVDM050 belongs to the SN65LVDM179, SN65LVDM180, SN65LVDM050, and SN65LVDM051 series which are differential line drivers and receivers that use low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbps. This modification provides a minimum differential output voltage magnitude of 247 mV into a 50-W 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-W characteristic impedance. The transmission media may be printed-circuit board traces, backplanes, or cables. These circuits are similar to TIA/EIA-644 standard compliant devices (SN65LVDS) counterparts, except that the output current of the drivers is doubled.
