ADCLK950 is an ultra-fast clock fan-out buffer manufactured using Analog Devices' proprietary XFCB3 silicon-germanium (SiGe) bipolar process and designed for high-speed applications requiring low jitter.
The device has two differential inputs that are selected via IN_SEL control pins. Both inputs are equipped with center tap, differential, 100 Ω in-chip termination resistors and accept DC-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and AC-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. VREFx pins are provided for biasing AC-coupled inputs.
ADCLK950 has 10 built-in full-swing emitter coupled logic (ECL) output drivers. For LVPECL (positive ECL) operating mode, VCC is biased to positive power and VEE bias to ground. For ECL operating mode, VCC bias to ground and VEE bias to negative power.
The output stage is designed to drive 800 mW directly from each end to a 50-Ω load terminated at VCC− 2 V, resulting in a total differential output swing of 1.6 V.
ADCLK950 is available in a 40-pin LFCSP package and is rated for an operating temperature range of −40°C to +85°C standard industrial temperature range.
