Product Introduction

Overview

The ADCLK946BCPZ is an ultrafast clock fanout buffer manufactured by Analog Devices Inc. using their proprietary XFCB3 silicon germanium (SiGe) bipolar process. This device is designed for high-speed applications that require low jitter, making it suitable for various demanding environments such as wireless infrastructure, instrumentation, networking, and more.

The ADCLK946BCPZ features a differential input with center-tapped, differential, 100 Ω on-chip termination resistors. It accepts a variety of input signals including dc-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. The device also includes a VREF pin for biasing ac-coupled inputs.
