LVDS driver, not a transceiver — why that matters for your link budget
The Texas Instruments SN75LVDS84DGGRG4 is a unidirectional LVDS driver from the FlatLink™ series — 4 driver outputs and zero receiver inputs, so it's a transmit-only device for pushing parallel data over a differential pair. If your design expects bidirectional communication or a receiver on the same chip, this isn't the part: you'd need a full LVDS transceiver with matched driver/receiver count.
Package reality: 48-TSSOP fine-pitch placement
The SN75LVDS84DGGRG4 comes in a 48-TFSOP (0.240", 6.10mm Width) body, also listed as a 48-TSSOP supplier device package. That's a fine-pitch TSSOP — likely 0.4mm or 0.5mm lead pitch — so the stencil aperture and solder paste volume need attention to avoid bridging. The Tape & Reel (TR) packaging is pick-and-place ready for volume assembly.
