Available in half- and full-duplex versions, ADI's ADN469xE transceivers are fully compliant with the TIA/EIA-899 M-LVDS
The DS91M040 also includes pin-control of the M-LVDS receiver, which allows designers to enable a receiver failsafe (type 2) or provide no failsafe (type 1) depending on the application.
Technical Features - DS91M040 Quad M-LVDS Transceiver
To date, customers converting M-LVDS to LVTLL for multi-drop clock distribution have used transceivers with unnecessary integrated driver circuitry.
The SN65MLVD2 type-1 M-LVDS receiver provides the best noise margin with switching occurring near the zero volt (differential) input level.
National Semiconductor designed the M-LVDS transceivers specifically for multipoint bus applications where a common bus connects multiple drivers and receivers.
The Advanced Telecom and Computing Architecture (ATCA) standard specifies M-LVDS as the interface for backplane synchronization clocks.
The MLVD047 is a quadruple M-LVDS line driver for 30-ohm to 55-ohm loads and data rates up to 200 Mbps or clock frequencies up to 100 MHz.
M-LVDS is the only LVDS standard for use on buses that provides the controlled edge rates, increased drive strength, improved thresholds and contention provisions that enable the flexible distributed clock distribution scheme specified by the AdvancedTCA specification of the PCI Industrial Computer Manufacturers Group.
National and TI have agreed to the inclusion of the 75176, 75180, 34050, 34051, LV047 and LV048 industry-standard footprints on their M-LVDS product roadmaps to provide low-power, low electromagnetic interference (EMI) and high-speed upgrades to existing components.
The standardization of M-LVDS will provide a new catalyst for the growth of the LVDS technology," said Guy Nicholson, interface marketing director of Wired Communications Division at National Semiconductor.
As an extension of the TIA/EIA-644 (LVDS) standard with point-to-point signaling that is already widely used for high-speed communications, the M-LVDS
standard targets multipoint applications while offering the benefits of low voltage differential signaling.
