SN65LVDM050, andSN65LVDM051aredifferen-  
tial line drivers and receivers that use low-voltage  
differential signaling (LVDS) to achieve signaling  
rates as high as 400 Mbps. 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 50-Ω  
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-Ω  
characteristic impedance. The transmission  
media may be printed-circuit board traces,  
backplanes, or cables.
