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.
