LVDS quad driver for 800 Mbps serial links
The MAX9123EUE+ is a quad LVDS line driver from Analog Devices, designed to push serial data at 800 Mbps over differential pairs. It packs four drivers into a 16-TSSOP package, drawing from a 3V to 3.6V supply rail — a direct fit for 3.3V logic systems. The industrial temperature range (-40°C to 85°C) suits it for outdoor telecom, factory-floor backplanes, and motor-drive encoder links where the ambient stays below 85°C.
800 Mbps — what it means for the link budget
At 800 Mbps, this driver handles 800 Mbps NRZ data per channel. The 3.3V supply keeps the output swing within standard LVDS levels, so it mates directly to LVDS receivers without level translation.
