854S54AKI-01LFT

Overview

The Renesas 854S54AKI-01LFT is a high-performance 4:1 differential-to-LVDS clock multiplexer designed for demanding signal integrity applications. It operates with a maximum output frequency of 2.5 GHz and accepts four selectable differential input pairs (PCLK, NPCLK) supporting LVPECL, LVDS, or CML logic levels. The device translates any single-ended input signal to LVDS levels using resistor bias on the NPCLK input. Key electrical specifications include an RMS additive phase jitter of 0.147 ps (typical), a part-to-part skew of 300 ps (maximum), and a propagation delay of 700 ps (maximum). It functions within a supply voltage range of 3.135 V to 3.465 V and supports an ambient operating temperature from -40°C to +85°C.
