ADCLK948是一款超快时钟扇出
bumper，采用ADI公司专有的XFCB3硅-锗（SiGe）双极性工艺制造，设计用于要求低抖动的高速应用。
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.
ADCLK948内置8个全摆幅射极耦合逻辑（ECL）输出驱动器。对于LVPECL（正ECL）工作模式， V
CC 偏置至正电源， V
EE 偏置至接地。对于ECL工作模式， V
CC 偏置至接地， V
EE 偏置至负电源。
The output stage is designed to drive 800 mW directly from each end to a 50-Ω load terminated at VCC -2V, resulting in a total differential output swing of 1.6 V.
ADCLK948 is available in a 32-pin LFCSP package and is rated for a standard industrial temperature range of −40°C to +85°C.
