What this clock buffer does and where it fits
The Renesas 8SLVP2102ANLGI/W is a 1:2 fanout buffer for high-speed clock distribution. It takes a single differential input — CML, LVDS, or LVPECL — and delivers two LVPECL outputs. The part runs up to 2 GHz, so it is aimed at telecom line cards, data-center switches, test equipment, and any board where a clean clock tree needs to split a reference without loading the source. Two independent buffer circuits are inside the 16-VFQFN package, each with its own 1:2 fanout. Supply voltage spans 2.375 V to 3.465 V. The operating temperature range is -40°C to 85°C, so it handles industrial environments — outdoor base stations, motor-drive control boards, and factory-floor Ethernet switches. The 3 mm × 3 mm QFN footprint is compact enough for dense line cards.
2 GHz bandwidth — what it means for your clock tree
A 2 GHz maximum frequency means this buffer can pass high-speed reference clocks without adding jitter from bandwidth limiting. The differential input and output path (Yes/Yes per the spec) means the part preserves common-mode rejection along the clock distribution. That matters when the clock source is across a backplane or through a long cable run where ground noise is a concern.
Signal compatibility — CML, LVDS, LVPECL in, LVPECL out
The input accepts three differential standards: CML, LVDS, and LVPECL. That is useful when the clock source is an FPGA (often LVDS), a high-speed ADC (CML), or a dedicated PLL (LVPECL). The output is always LVPECL, so the downstream receivers must be LVPECL-compatible or you need an AC-coupling network with a DC bias.
Sourcing and lifecycle — active, no LTB worry
ROHS3 compliant. For new designs or BOM fills, there is no last-time-buy pressure. We source it through independent distribution and quote against an RFQ with current availability and pricing confirmed at quote time.
