DescriptionThe SN65MLVD200A, 202A, 204A, and 205A are multipoint-low-voltage differential (M-LVDS) line drivers and receivers, which 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. SN65MLVD200A, 202A, 204A, and 205A 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 , and incorporates controlled transition times to allow for stubs off of the backbone transmission line.
SN65MLVD200A, 202A, 204A, and 205A 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 SN65MLVD200A, 202A, 204A, and 205A 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 fault conditions.
The SN65MLVD200A, 202A, 204A, and 205A have enhancements over their predecessors. Improved features include better controlled slew rate on the driver output to help minimize reflections while improving overall signal integrity (SI) resulting in better jitter performance. Additionally, 8-kV ESD protection on the bus pins of SN65MLVD200A, 202A, 204A, and 205A for more robustness. The same footprint definition was maintained making for an easy drop-in replacement for a system performance upgrade.
The SN65MLVD200A, 202A, 204A, and 205A are characterized for operation from -40 to 85.
