DESCRIPTION

The SN65MLVD201, 203, 206, and 207 are

multipoint-low-voltage differential (M-LVDS) line

drivers and receivers, which are optimized to operate at signaling rates up to 200 Mbps. All parts comply

with the multipoint low-voltage differential signaling

M-LVDS) standard TIA/EIA-899. These circuits are

similar to their TIA/EIA-644 standard compliant LVDS

counterparts, with added features to address

multipoint applications. The driver output has been

designed to support multipoint buses presenting loads as low as 30 Ω, and incorporates controlled

transition times to allow for stubs off of the backbone

transmission line.

These devices have Type-1 and Type-2 receivers

that detect the bus state with as little as 50 mV of

differential input voltage over a common-mode

voltage range of -1 V to 3.4 V. The Type-1 receivers

exhibit 25 mV of differential input voltage hysteresis

to prevent output oscillations with slowly changing

signals or loss of input. Type-2 receivers include an

offset threshold to provide a known output state

under open-circuit, idle-bus, and other faults

conditions. The devices are characterized for

operation from –40°C to 85°C.
