It is not a differential buffer — both input and output are single-ended (No/No for differential I/O), so it fits standard CMOS clock trees where you need to split a reference clock to multiple loads without adding a PLL or divider. The 1:4 ratio is useful for fanning a master oscillator to several peripherals — MCU, Ethernet PHY, FPGA bank — while keeping the drive strength clean. ## Supply voltage and temperature grade The supply range spans 1.71 V to 3.465 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without needing a separate regulator. The operating temperature range of -40°C to 105°C qualifies it for industrial environments — outdoor telecom cabinets, motor drive controllers, and factory automation panels where the ambient can push past 85°C. The 105°C ceiling gives thermal margin for designs with limited airflow or proximity to hot power stages. ## Package and footprint Housed in an 8-UFDFN package (supplier device package 8-VFQFN, 2x2 mm), this is a small surface-mount device suited for dense PCB layouts. The 2x2 mm footprint and 0.5 mm pitch are typical for a low-pin-count clock buffer; the exposed pad (if present) should be stitched to ground with a via array under the package for thermal relief. The part is surface-mount only — no through-hole option. ## Lifecycle and sourcing For dual-sourcing resilience, the Renesas 5PB1104CMGK/W is a functional peer with the same LVCMOS output type, 1:4 ratio, and 200 MHz ceiling — though the package variant differs (Tape & Reel vs Strip). The 621SCMGI is quoted to order through independent distribution; availability and current pricing are confirmed at RFQ time.","metaTitle":"Renesas 621SCMGI Fanout Buffer, 1:4 LVCMOS, 200 MHz, 8-VFQFN","metaDescription":"Renesas 621SCMGI fanout buffer distributes one clock input to four LVCMOS outputs at up to 200 MHz.
