2 GHz fanout buffer — what it means for the clock tree
The Renesas 8SLVP1102ANLGI is a 1:2 differential fanout buffer designed to distribute high-speed reference clocks without adding jitter. It accepts CML, LVDS, or LVPECL inputs and produces two LVPECL outputs at up to 2 GHz — the kind of signal a 10+ Gbps SERDES or a high-speed ADC expects. The 16-VFQFN package with an exposed pad (3x3 mm footprint) sinks heat through the board, so the thermal via pattern under the pad matters more than airflow for keeping junction temperature inside the -40 to 85°C operating range.
Supply range and input flexibility
Supply voltage spans 2.375 V to 3.465 V, covering 2.5 V and 3.3 V logic rails. The input stage accepts three differential standards — CML, LVDS, LVPECL — without external level shifting, which simplifies BOM integration when the source is a FPGA bank or a crystal oscillator module. All signal paths are fully differential (input and output), so common-mode noise rejection is inherent; no single-ended mode available.
Package and mounting — what the rework tech sees
The 16-VFQFN package (3x3 mm, 0.5 mm pitch) has an exposed thermal pad underneath. On a rework station, the pad needs a stencil aperture big enough to deposit solder paste across the full pad area — a standard QFN profile at 240°C peak works. The part ships in tube, not tape-and-reel, so automated pick-and-place lines need a tube feeder or manual tray loading. No lab, no bench — just a hot-air pencil and a steady hand, but make sure the pad is tinned evenly or the part tilts.
Lifecycle and compliance
Listed as Active in production with ROHS3 compliance. The successor or second-source matrix is straightforward: the 8SLVP1104ANLGI (1:4 fanout, same package and input types) is the closest functional sibling if the design needs four outputs instead of two.
