1.2 GHz clock distribution — one input, six outputs
The ADCLK846BCPZ-REEL7 is a 1:6 fanout buffer from Analog Devices, rated for a maximum frequency of 1.2 GHz. It accepts any of five input standards — CML, CMOS, HSTL, LVDS, or LVPECL — and outputs CMOS or LVDS, making it a universal clock fanout for high-speed ADC, DAC, FPGA, or SerDes reference clock trees. A single input drives six differential or single-ended outputs, preserving signal integrity across the fanout. The 1.2 GHz ceiling covers most RF sampling clocks and gigabit serial links, but falls short of multi-GHz SerDes rates — for those, consider the SiGe-based ADCLK944BCPZ-R7 with 7 GHz capability.
Supply rail and temperature — 1.8V nom, -40 to 85°C
The supply voltage range is 1.71V to 1.89V, nominally 1.8V. This is a dedicated 1.8V-only rail — do not connect to 2.5V or 3.3V without a local LDO. The operating temperature spans -40°C to 85°C, qualifying it for industrial and telecom environments where ambient heat or cold is a factor. The 24-LFCSP (4x4 mm) package with exposed pad requires a thermal via array under the pad for heat sinking. The pad is electrically connected to ground — ensure the PCB landing pattern matches the supplier device package recommendation for 24-LFCSP.
Active lifecycle — tape-and-reel production packaging
RoHS3 compliance is confirmed. No AEC-Q100 qualification is listed, so this part is not formally rated for automotive use.
Sourcing and BOM fit
The closest functional alternative is the ADCLK854BCPZ-REEL7, a 2:12 fanout buffer/multiplexer in the same 24-LFCSP package, but its 2-input mux and 12-output fanout change the BOM topology. For a 1:6 fanout, the ADCLK846BCPZ-REEL7 is the correct choice. Quoted to order against BOM quantity. No stock-holding claim — confirm lead time and pricing at RFQ.
