What the dual supply range means for your power rail
The SN65LVDS4RSER is a single LVDS receiver from TI's 65LVDS family, rated for 500 Mbps and packaged in a 10-UQFN (2.0x1.5 mm). That dual-range flexibility simplifies the power tree in mixed-voltage designs, but it also demands two clean supply domains with their own decoupling; sharing a single 2.5 V rail and ignoring the lower range leaves the receiver's common-mode input range unsupported at the low end.
It remains a viable choice for new production builds and BOMs that need a known-good LVDS receiver without obsolescence overhead. The base product number is 65LVDS4, and the RSER suffix denotes the specific reel and package variant.
Industrial temperature and 10-UQFN footprint
The 10-UQFN (2.0x1.5 mm) package is a fine-pitch, leadless land-grid array — the PCB land pattern must match the supplier device package dimensions exactly, and the exposed pad (if present) should be stitched to a ground plane with thermal vias to keep junction temperature under control during continuous 500 Mbps operation.
