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.
At 622 Mbps, this driver can handle OC-12 / STM-4 line rates cleanly, which puts it in the sweet spot for SONET/SDH framers, serial backplanes, and video transport links running SMPTE 292M (HD-SDI). 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
No exposed pad, so thermal dissipation is through the leads and the copper pour on the board. 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.
Lifecycle and compliance
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.
