That 1.2 GHz ceiling means it can distribute a 1 GHz ADC sampling clock or a 156.25 MHz Ethernet reference with plenty of margin — the buffer itself is rarely the bottleneck. It accepts CML, CMOS, HSTL, LVDS, and LVPECL inputs and outputs CMOS or LVDS. The input flexibility is the key feature here: you can feed it from a crystal oscillator, a PLL synthesizer, or a serializer output without adding a level-shifter. ## Supply rail and temperature grade The supply range is 1.71V to 1.89V, which maps to a nominal 1.8V rail. The 180 mV tolerance means the rail needs a low-noise LDO — a switcher with 50 mV ripple will push the output jitter above the buffer's own additive jitter floor. Operating temperature spans -40°C to 85°C, covering industrial and telecom outdoor enclosures. The 24-LFCSP (4x4) package with exposed pad requires a thermal via array under the paddle to keep the junction below the derating threshold at 1.2 GHz. ## Active production — no end-of-life risk The tray package is the standard delivery form for volume assembly. For smaller quantities, the ADCLK846BCPZ-REEL7 variant ships in tape and reel — electrically identical, same 24-LFCSP footprint. ## Input and output signal compatibility Differential input and output paths are supported, which preserves signal integrity over longer PCB traces. The single-circuit design means one buffer IC handles one clock input and fans it to six outputs — no daisy-chaining needed for a six-way split. Surface-mount mounting in the 24-WFQFN exposed pad package requires a solder stencil aperture covering at least 50% of the pad area to avoid voids under the thermal slug.","metaTitle":"ADCLK846BCPZ Clock Buffer 1:6 1.2GHz 24-LFCSP – Analog","metaDescription":"ADCLK846BCPZ fanout buffer, 1:6 ratio, 1.2 GHz max, 1.8V supply, multi-protocol input.
