• TSSOP-20 surface mount package
• 3.3V operating voltage

Applications

• PCI Express clock distribution systems

Procurement Notes

Verify the manufacturer part number 557G-06LFT against official Renesas documentation to confirm pinout and electrical specifications. Check for the ICS557G-06LFT alias in legacy databases. Ensure the TSSOP-20 package variant matches the design requirements before procurement.

Selection Notes

Select this component for designs requiring a 2-to-4 channel PCI Express clock multiplexer. Confirm that the TSSOP-20 package dimensions fit the PCB layout constraints. Verify that the 3.3V supply voltage aligns with the system power architecture and that the specific series characteristics meet the jitter and frequency requirements.

Part Context

This component is part of the broader 557G family of clock generators and support products from Renesas Electronics. It shares the base 557G product line identifier but is distinguished by the -06 suffix indicating its specific mux configuration and the LFT suffix denoting lead-free packaging compliance.
