Quad LVDS receiver for point-to-point and multidrop links
The Texas Instruments DS90LV048ATMTCX/NOPB is a quad-channel LVDS receiver designed to convert low-voltage differential signals back to CMOS logic levels. It handles four independent channels, each rated for 400 Mbps, making it a fit for high-speed serial links in industrial video, camera interfaces, and backplane data distribution.
400 Mbps per channel — signal integrity margin
At 400 Mbps per channel, the receiver supports LVDS links with a 2.5 ns bit period. That leaves enough setup-and-hold margin for most 100–200 MHz pixel clocks or serial data streams after accounting for cable skew and connector jitter. The input threshold is LVDS-standard (typically ±100 mV), so it works with any LVDS driver that meets the TIA/EIA-644 specification. If your link runs at a lower rate, the receiver simply tracks the slower edges with no extra configuration.
16-TSSOP package and rework considerations
The part comes in a 16-TSSOP package with a 0.173" body width and 0.65 mm lead pitch. That's a standard fine-pitch SOIC footprint — easy to inspect and rework with a hot-air station if needed. The leads are visible after soldering, so a quick visual check confirms alignment. No exposed pad underneath, which simplifies the PCB layout and eliminates any thermal-via stitching requirement. The NOPB suffix indicates lead-free (NiPdAu) finish, so it's RoHS-compatible and reflows well with standard SAC solder profiles.
The base product number DS90LV048 covers a family of quad LVDS receivers in various package and temperature options, so if your BOM needs a different variant (e.g., the DS90LV048ATMTC without the NOPB suffix), the active status holds across the family. For a production line, this part carries no near-term obsolescence risk.
