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. • Single 3.3V Power Supply Design • Driver: — ±350mV Differential Swing into a 50 ohm load — Propogation Delay of 1.5ns Typ. — Low Voltage TTL (LVTTL) Inputs are 5V Tolerant — Driver is High Impedance when Disabled or VCC < 1.5V • Receiver: — Accepts ±50mV (min.) Differential Swing with up to 2.0V ground potential difference — Propagation Delay of 3.3ns Typ. — Low Voltage TTL (LVTTL) Outputs — Open, Short, and Terminated Fail Safe • Industrial Temperature Operating Range: –40°C to 85°C The drivers translate a low-voltage TTL/CMOS input into a lowvoltage (350mV typical) differential output signal into a 50-ohm load. The receivers translate a differential 350mV 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). • Package Options: SOIC, TSSOP, MSOP Applications • Bus-Terminal ESD > 12kV 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 communi- cations; PBXs, switches, repeaters and base stations for telecommunications and other applications such as digital cameras, printers and copiers.
