The DS90LV047ATMX: Each of the four drivers handles up to 400 Mbps, making this part suitable for point-to-point or multidrop backplane interfaces, display links, and camera-serializer outputs in industrial and telecom equipment.
The DS90LV047ATMX carries an official obsolete status. TI no longer manufactures this specific variant, so new-production orders through the factory channel are not available. Sourcing is limited to the independent distribution and surplus market, where inventory turns over quickly and date codes vary. For a BOM that requires this exact order code, the procurement path is a quoted-to-order RFQ through a broker or specialty distributor who can locate remaining stock.
400 Mbps per channel — what the data rate buys you
Each of the four drivers independently operates at 400 Mbps. The 16-SOIC package has a 3.90 mm width.
Pin 1 orientation and rework notes
The 16-SOIC narrow package has a standard pin 1 identifier — a molded notch and a dot on the top surface. The part is MSL 3 per the TI family data, so if the moisture-barrier bag has been open longer than the floor-life window, bake it at 125°C for 24 hours before reflow. No exposed thermal pad on this package, so all heat dissipation goes through the leads — derate the junction temperature if driving all four channels at full rate in a 85°C ambient.
