The DS90LV047ATMX/DRPB: It pushes 400 Mbps per channel over twisted-pair or PCB traces, common in flat-panel display interfaces, backplane data distribution, and camera serial links.
400 Mbps and the 16-SOIC footprint
The 400 Mbps data rate per driver is the headline spec for this part — it determines the maximum serial bitstream the device can cleanly launch before jitter and skew eat into the receiver's setup-and-hold window. In practice, that rate supports 24-bit RGB video at 60 Hz over a four-lane link, or aggregating multiple slower serial streams.
No official successor on record
No official TI replacement order code is listed for the DS90LV047ATMX/DRPB. That means there is no factory-recommended drop-in from the same vendor. For a new design, a pin-compatible LVDS quad driver from another manufacturer — same 16-SOIC footprint, same 3.3V supply, same 400 Mbps class — would need to be qualified against the original's output swing, common-mode range, and skew specs. For repair or retrofit of an existing board, sourcing the original part through independent distribution is the only way to avoid a layout change.
