2 GHz LVDS fanout — where the 2:4 ratio fits
The 8SLVD2102NLGI is a 2:4 differential fanout buffer from Renesas, accepting LVDS or LVPECL inputs and delivering LVDS outputs at frequencies up to 2 GHz. The 2:4 ratio means two input channels each fan out to two outputs — useful for splitting a reference clock to multiple SERDES transceivers or FPGA banks without adding separate PLLs. The 2.375V to 2.625V supply range centres on 2.5V. If your board already has a 2.5V supply for the FPGA transceiver bank, this buffer can share it.
Supply rail and temperature grade — BOM-fit checks
Compared to the LVPECL-output sibling 8SLVP1104ANLGI (1:4, 3.135V supply), the 8SLVD2102NLGI runs on a lower 2.5V rail and outputs LVDS, which consumes less power and simplifies termination — no pull-up resistors to VCC-2V. The 8SLVP1204ANLGI8 adds a multiplexer function but still outputs LVPECL. For a pure LVDS fanout at 2 GHz, this is the direct fit.
