Key Features
- Dual-port 2:1/1:2 LVDS multiplexer and repeater/buffer
- High-speed data paths with flow-through pinout to minimize internal device jitter and simplify board layout
- Configurable pre-emphasis to overcome Inter-Symbol Interference (ISI) jitter effects from lossy backplanes and cables
- LVDS/BLVDS/CML/LVPECL compatible inputs and LVDS compatible outputs
- Output enable control on each of the six onboard LVDS output drivers, allowing individual channels to be placed in a low power TRI-STATE mode
- Powerdown mode that consumes only 0.5mA (typical) of supply current when all output enables are deasserted
- Internal 100 ohm termination resistor for minimal reflections
