That ratio matters when you have a single high-frequency reference (say, from an oscillator or PLL) that needs to drive multiple downstream devices like SERDES, FPGAs, or ADCs without loading the source. Rated for 1.5 GHz maximum frequency, this buffer handles common telecom and data-center clock rates including 156.25 MHz, 312.5 MHz, and 625 MHz with margin. The differential input accepts CML, LVPECL, or SSTL levels, so it sits between a wide range of clock sources and the LVPECL fanout tree. ## Supply range, temperature grade, and signal integrity The wide tolerance means you can run it off a 3.3 V supply that droops under load and still stay within spec. The 32-VFQFPN (5x5 mm) exposed-pad package helps pull heat out of the die when the buffer is driving twelve 50-ohm terminated lines at full rate. Differential input and output paths (Yes/Yes per the spec) reject common-mode noise on the clock lines — critical when routing high-speed clocks across a board with switching regulators or digital busses nearby. Listed as Active by Renesas with ROHS3 compliance. Supplied in tray packaging, surface-mount to a 32-VFQFN exposed-pad footprint.","metaTitle":"Renesas 853S12AKILF Fanout Buffer, 1:12, 1.5 GHz","metaDescription":"Active Renesas 853S12AKILF 1:12 fanout buffer, 1.5 GHz max, LVPECL output, CML/LVPECL/SSTL input, 32-VFQFPN, -40 to 85°C.
