853S111BYILFT

Overview

The 853S111BYILFT is a low skew, high performance 1-to-10 Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer manufactured by Renesas Electronics Corporation. It operates from either a 2.5V or 3.3V power supply with an output frequency of up to 2.5 GHz. The device features two selectable differential input pairs (PCLKx, nPCLKx) capable of accepting LVPECL, LVDS, and SSTL levels. Key electrical parameters include a maximum output skew of 50 ps, part-to-part skew of 150 ps, propagation delay of 645 ps, and typical additive phase jitter of 0.03 ps RMS. It is housed in a 32-pin PTQFP package.
