854S054AGILF

Overview

The 854S054AGILF is a high-speed 4:1 differential-to-LVDS clock multiplexer manufactured by Renesas Electronics. It operates with four selectable differential clock inputs (PCLK, NPCLK) capable of accepting LVPECL, LVDS, or CML signal levels. The device translates any single-ended input signal to LVDS levels using resistor bias on the NPCLKX input. Key electrical parameters include a maximum output frequency of 2.5 GHz, a typical additive phase jitter of 0.147 ps RMS, and a maximum propagation delay of 700 ps. 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.

Feature Summary

• Supports four selectable differential PCLK/NPCLK input pairs compatible with LVPECL, LVDS, and CML standards.
• Translates single-ended input signals to LVDS levels via internal resistor biasing on the NPCLKX input.
• Features low part-to-part skew of 300 ps maximum and typical additive phase jitter of 0.147 ps RMS.
• Select pins include internal pull-down resistors; SEL1 serves as the most significant bit for binary selection.

Applications

• Clock distribution circuits requiring high-speed differential signal routing.
• Systems utilizing PCLK/NPCLK differential clock architectures.
• Voltage translation applications converting various differential logic levels to LVDS.

Part Context

The 854S054I belongs to the Renesas family of high-performance clock solutions. This specific variant is packaged in a 16-lead TSSOP format with dimensions of 5.0 x 4.4 x 1.0 mm and a 0.65 mm pitch. It is available in lead-free packages compliant with RoHS 6 standards.

Replacement Considerations

The 854S058I is identified as a functional replacement offering 8:1 multiplexing capability. Designers should verify pinout compatibility and ensure the higher channel count does not impact board layout constraints.
