Full-duplex LVDS transceiver at 400 Mbps — what the ratings mean for a backplane or cable run
The SN65LVDS049PW is a full-duplex LVDS transceiver with two drivers and two receivers on a single 16-TSSOP die — 2/2 configuration means one differential pair each for transmit and receive, so a point-to-point link does not need a separate direction-control pin. Rated at 400 Mbps per channel, the data rate ceiling is set by the driver output transition time and the receiver input threshold hysteresis — in practice this supports backplane clock distribution at 200 MHz or a serialised data stream over a single twisted pair at the full rate, as long as the cable length stays within the LVDS common-mode range (0.2 V to 2.2 V typical).
Package footprint and board-level integration
Surface-mount only; the tube packaging is typical for prototype or low-volume builds — for reeled quantities the base product number 65LVDS049 supports tape-and-reel options if the BOM volume justifies it.
Lifecycle and compliance — no obsolescence watch needed
ROHS3 compliant — the part is free of the ten restricted substances plus four phthalates, which clears EU and UKCA markets without an exemption declaration.
