The SN65MLVD128 and SN65MLVD129 are LVTTL-to-M.LVDS translators/repeaters. Outputs comply with the M.LVDS standard (TIA/EIA-899) and are optimized for data rates up to 250 Mbps, and clock frequencies up to 125 MHz. The driver outputs have been designed to support multipoint buses presenting loads as low as 30 and incorporates controlled transition times for backbone operation.

M-LVDS compliant devices allow for 32 nodes on a common bus, providing a high-speed replacement for RS-485 devices when lower common-mode voltage range and lower output signaling levels are acceptable. The SN65MLVD128 and SN65MLVD129 provide separate driver enables, allowing for independent control of each output signal.

Intended applications for these devices include transmission of clock signals from a central clock module, as well as translation and buffering of data or control signals for transmission through a controlled impedance backplane or cable.
