Overview
The ADCLK948BCPZ-REEL7 is an ultrafast clock fanout buffer designed by Analog Devices Inc. It is fabricated on the proprietary XFCB3 silicon germanium (SiGe) bipolar process, making it ideal for high-speed applications that require low jitter. This device features two selectable differential inputs via the IN_SEL control pin, each equipped with center-tapped, differential, 100 Ω on-chip termination resistors. It supports a variety of input types, including dc-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs.
