What this part is and where it fits
The ADN4668ARZ from Analog Devices is a quad LVDS receiver — four independent receivers in a single 16-SOIC package. It handles 400 Mbps per channel over a differential pair, making it a standard choice for point-to-point or multidrop backplane links, camera serial interfaces, and clock distribution in industrial or telecom gear. The 3V to 3.6V supply rail means it runs clean off a 3.3V supply; no 5V tolerance here, so check your rail before you drop it in.
Key ratings and what they mean for the BOM
The 400 Mbps data rate is specified for the part. The -40°C to 85°C industrial temperature range is listed. Four receivers in one package. The 0/4 driver/receiver count means this is purely a receiver.
Lifecycle and sourcing reality
The ADN4668ARZ is listed as Active — no end-of-life notice, no last-time-buy window looming. It's ROHS3 compliant, so no conflict with current environmental directives. For new designs, this part is a safe bet; you're not chasing a sunset part.
