With one driver and no receiver, this is a transmit-only buffer — the kind you'd use on the line card side of a backplane or a high-speed clock distribution path where you need to convert a single-ended signal to a differential LVDS pair.
The LVDS output swing is typically 350 mV into a 100 Ω termination, so the signal integrity budget at that speed demands controlled-impedance traces and a tight ground plane — not a routed-over-the-top layout. If your link margin is tight at 622 Mbps, the driver itself is not the bottleneck; the PCB and connector losses will dominate.
Supply and temperature — the operating envelope
A 3.3V LDO with 200 mV dropout at the driver's supply current keeps the rail inside the window even during line transients. At the cold end, LVDS output swing holds up — no startup issues down to -40°C as long as the supply is stable.
Package and footprint realities
At 622 Mbps, keep the output trace pair length-matched and the 100 Ω termination resistor within 5 mm of the receiver input. The supply decoupling should be a 0.1 µF ceramic as close to the supply pin as possible, with a 1 µF bulk cap nearby.
It is ROHS3 compliant, which means no exemptions for lead in solder — it ships fully RoHS-compatible. The /NOPB suffix specifically denotes the lead-free, RoHS-compliant version; the plain CLC001AJE is the older tin-lead variant, and the two are otherwise identical in function and footprint.
