ICS85454AK-01LF

Clock Buffers, Drivers Overview

The ICS85454AK-01LF is a dual 2:1/1:2 differential-to-LVDS multiplexer from the HiPerClockS family, manufactured by Integrated Circuit Systems (ICS). It features three LVDS outputs and three differential inputs capable of accepting LVPECL, LVDS, or CML levels. The device operates on a 2.5V supply with a maximum output frequency of 2.5GHz. Key electrical specifications include a part-to-part skew of 250ps maximum, additive phase jitter of 0.05ps typical, and propagation delay of 550ps maximum. It supports loopback testing and functions within an ambient temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Dual 2:1/1:2 Multiplexer architecture with three LVDS outputs
• Differential inputs accept LVPECL, LVDS, and CML signal levels
• Maximum operating frequency of 2.5GHz with 250ps max part-to-part skew
• Low additive phase jitter of 0.05ps RMS typical

Clock Buffers, Drivers Applications

• Multiplexing multi-rate Ethernet PHYs onto optical SFP modules
• Host bus adapter boards for routing between internal and external connectors
• Hot-swappable links to redundant switch fabric cards

Clock Buffers, Drivers Procurement Notes

Verify RoHS compliance status as the 'LF' suffix indicates lead-free packaging per manufacturer ordering information. Confirm package type is 16-lead VFQFN (3mm x 3mm) and check for specific tape-and-reel availability if required for automated assembly.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and high-speed multiplexing of differential clock signals are required. Ensure input drivers match the supported LVPECL, LVDS, or CML voltage swings. Consider thermal resistance (51.5°C/W at 0 lfpm) for junction temperature calculations in space-constrained designs.

Clock Buffers, Drivers Part Context

This device belongs to the ICS85454 series, specifically designed for high-performance clock solutions. It serves as a critical timing element in networking and telecommunications infrastructure, enabling flexible signal routing between different protocol domains or redundant system paths.

Clock Buffers, Drivers Replacement Considerations

Check for ICS85454 variants with different suffixes (e.g., standard leaded vs. lead-free) that maintain identical pinouts and electrical characteristics. Verify functional compatibility before substituting.
