854S1208AYILF

Overview

The 854S1208AYILF is a high-performance 2:1 differential-to-LVDS multiplexer manufactured by Renesas Electronics Corporation. It accepts two differential clock inputs, supporting LVPECL or LVDS signal levels, and provides one LVDS output pair. The device operates with a maximum input/output frequency of 2.5GHz. Key electrical characteristics include an RMS additive phase jitter of 0.06ps (typical), a maximum propagation delay of 600ps, and a maximum part-to-part skew of 350ps. It functions in a full 3.3V supply mode and is rated for an ambient operating temperature range of -40°C to 85°C.
