It accepts CML, CMOS, LVDS, or LVPECL inputs and delivers LVPECL outputs — so the same buffer can sit behind a PLL output or a crystal oscillator without needing a translator. ## Supply range and signal compatibility Supply voltage range is 2.97 V to 3.63 V, which aligns with a 3.3 V rail ±10 %. The differential input and output path means the buffer rejects common-mode noise on the clock trace — important when the source and load are on different boards connected by a cable. Compared to the ADCLK948BCPZ (2:8 fanout/mux) or ADCLK950BCPZ (2:10), this 1:6 part is the simpler fanout-only choice when you do not need input selection. ## Layout and thermal considerations The 24-VFQFN exposed-pad CSP requires a solder-paste stencil opening that covers at least 50 % of the pad area to avoid voids. The exposed paddle is the primary thermal path — connect it to a solid ground plane with at least four thermal vias under the pad. The 4.8 GHz bandwidth supports 10-GbE reference clocks and ADC sampling clocks without edge degradation.","metaTitle":"ADCLK946BCPZ Clock Buffer 1:6 4.8GHz LVPECL Analog Devices","metaDescription":"ADCLK946BCPZ SiGe fanout buffer, 1:6 ratio, 4.8 GHz max frequency, LVPECL output, industrial temp range -40°C to 85°C.
