That frequency ceiling covers the reference clock for most high-speed ADCs, DACs, and FPGAs on the market – the part does not become the bottleneck in the clock tree. All twelve outputs are differential LVPECL, which means the DC termination must be to VCC – a common pitfall for teams migrating from LVDS. ## Supply rail tolerance and decoupling reality The supply range is 2.97V to 3.63V – a 3.3V rail must stay within ±0.33V, so a 3.3V LDO with ±1% initial accuracy plus load transient headroom is the safe choice. The 40-LFCSP exposed paddle must be soldered to a ground plane with adequate thermal vias for both heat spreading and return current. ## Sourcing and lifecycle posture Sourced per RFQ; current availability and pricing confirmed at quote time.","metaTitle":"ADCLK954BCPZ-REEL7 – 4.8 GHz 2:12 LVPECL Fanout Buffer / Mux","metaDescription":"Analog Devices SiGe clock buffer, 2:12 mux, 4.8 GHz max, LVPECL outputs, 40-LFCSP, -40°C to 85°C, Active, ROHS3.
