That 2:12 ratio means a single device can feed a dozen high-speed loads — ADCs, FPGAs, or SerDes — without cascading multiple buffers, saving board area and reducing additive jitter from extra stages. Input compatibility spans CMOS, LVDS, and LVPECL levels, so the same part can interface with a crystal oscillator, a PLL output, or a backplane clock without external level shifters. The fully differential signal path (input and output) preserves common-mode rejection and keeps the clock clean through the distribution tree. ## Supply rail and temperature — staying inside the operating window The supply range is 2.97 V to 3.63 V, a tight 3.3 V nominal window. Plan for a low-noise LDO or a clean switching regulator with ripple below 10 mV to keep the clock jitter floor low. The 40-LFCSP-VQ (6x6) exposed-pad package requires a thermal via array under the pad to pull heat into the ground plane — without it, the junction temperature rises faster than the datasheet derating assumes. ## Active production — no EOL risk for current designs The part is in ongoing production at Analog Devices, and the tray package is the standard delivery format for volume assembly — no reel premium. ROHS3 compliant, so it passes EU material restrictions without an exemption. The 40-LFCSP package is lead-free compatible with standard Pb-free reflow profiles (260°C peak).","metaTitle":"ADCLK954BCPZ 4.8 GHz 2:12 LVPECL Fanout Buffer","metaDescription":"ADCLK954BCPZ SiGe clock buffer, 4.8 GHz max, 2:12 fanout, LVPECL outputs, -40°C to 85°C, 40-LFCSP.
