The SY89851UMG-TR is a 1:2 fanout buffer and translator from Microchip's Precision Edge® series, accepting CML, LVDS, or PECL inputs and delivering a single LVPECL output pair. Rated for a maximum frequency of 4 GHz, it handles the clock distribution for 10G+ serial links and high-speed data converters where edge placement matters.
All signal paths are differential (input and output), so the PCB traces should be routed as 100-Ω coupled pairs with matched length to preserve the 4 GHz bandwidth.
