This modification enables true half-duplex operation with more than one LVDS driver or with two line transmission resistors over a 50 ohm differential transmission line. These devices use low-voltage differential signaling (LVDS) to achieve data rates in excess of 660 Mbps while being less susceptible to noise than single-ended transmission. The drivers translate a low-voltage TTL/CMOS input into a lowvoltage (350m V typical) differential output signal into a 50-ohm load. The receivers translate a differential 350m V input signal to a 3V CMOS output level. Driver section can be independently set to a power-down and high-impedance output mode with the DEN pin (active HIGH). Receiver section is controlled by the REN- pin (active LOW). Applications Applications include point-to-point and multidrop baseband data transmission over a controlled impedance media of approximately 50 ohms. These include intra-system connections via printed circuit board traces or cables, hubs and routers for data muni- cations; PBXs, switches, repeaters and base stations for telemunications and other applications such as digital...
