3 Description

The SN65MLVD20xx devices are multipoint lowvoltage

differential (M-LVDS) line drivers and

receivers that are optimized to operate at signaling

rates up to 100 Mbps. All parts comply with the

multipoint low-voltage differential signaling (M-LVDS)

standard TIA/EIA-899.

The SN65MLVD20xx devices have enhancements

over their predecessors. Improved features include

controlled slew rate on the driver output to help

minimize reflections from unterminated stubs, which

results in better signal integrity. Additionally, 8-kV

ESD protection on the bus pins for more robustness.

The same footprint definition was maintained making

for an easy drop-in replacement for a system

performance upgrade.

The devices are characterized for operation from –

40°C to 85°C.
