854S54AKILF

Overview

The Renesas Electronics 854S54AKILF is a dual differential-to-LVDS multiplexer featuring one 2:1 and one 1:2 configuration. It operates at a maximum frequency of 2.5 GHz with a 2.5 V supply voltage (2.375 V to 2.625 V). The device accepts LVPECL, LVDS, or CML inputs and provides three differential LVDS output pairs. Key electrical parameters include a typical additive phase jitter of 0.053 ps RMS and a maximum propagation delay of 480 ps for the QA/nQA path. It is housed in a 16-lead VFQFN package.

Feature Summary

• Dual multiplexing architecture combining a 2:1 MUX and a 1:2 MUX
• Maximum operating frequency of 2.5 GHz
• Accepts LVPECL, LVDS, and CML differential input levels
• Typical additive phase jitter of 0.053 ps RMS

Applications

• Multiplexing multi-rate Ethernet PHY transmit/receive pairs onto optical SFP modules
• Clock distribution circuits requiring high-performance signal selection
• Voltage translation applications between different logic families

Procurement Notes

Verify RoHS compliance status via official documentation before procurement. Confirm that the specific ordering suffix matches the required packaging format, as tube and tape & reel options exist within the product family. Ensure the component meets the specified ambient temperature range requirements for the target application environment.

Selection Notes

Select this component when a single package must handle both 2:1 and 1:2 differential multiplexing functions. Verify that the system power budget accommodates the maximum supply current of 82 mA. Ensure the PCB layout supports the thermal requirements of the exposed pad VFQFN package to maintain junction temperatures below the 125°C limit.

Part Context

This device belongs to the ICS854S54I series of clock multiplexers. It serves as a functional replacement for the ICS85454 part number. The manufacturer transitioned from Integrated Device Technology (IDT) to Renesas Electronics, maintaining pin and function compatibility across the product lineage.

Replacement Considerations

The datasheet identifies the ICS85454 as a compatible predecessor. This device offers pin and function compatibility with the ICS85454.
