It handles input and output as plain clock signals, so no CML or LVPECL translation is needed on the board. Maximum frequency is 200 MHz — adequate for most Ethernet, FPGA reference, and base-station clock trees. The supply voltage spans 1.71V to 3.465V, covering 1.8V, 2.5V, and 3.3V rails without an extra regulator. ## Industrial temperature and package fit The 8-UFDFN package with a 2x2 mm body saves board space — the 0.50 mm pitch demands a controlled solder profile but fits tight layouts. Non-differential I/O means the input and output are single-ended; the buyer avoids the termination resistor network that differential buffers require. The 1:4 ratio matches the most common fanout for splitting a master clock to four PLLs or ASICs.","metaTitle":"551SCMGI Renesas 1:4 Fanout Buffer – 200 MHz, 8-UFDFN","metaDescription":"Renesas 551SCMGI fanout buffer, 1:4 ratio, 200 MHz max, 1.71V–3.465V supply, -40°C to 105°C, 8-UFDFN package.
