557MI-01LFT

Overview

The Renesas 557MI-01LFT is a clock generator designed for PCI Express applications. It utilizes a phase-locked loop (PLL) to convert a 25 MHz crystal input into a 100 MHz output. The device provides one differential HCSL output pair and supports LVDS signal levels via alternative termination. Packaged in an 8-pin SOIC, it operates on a 3.3V supply with a typical power consumption of 182 mW. The component functions within an industrial temperature range of 0°C to +70°C.

Feature Summary

• PCI Express Gen1 compliant clock source
• HCSL differential outputs at 100 MHz
• LVDS support via alternative termination
• Low power consumption (182 mW typ.)

Applications

• PCI Express cards as a clock source
• PCIE Gen2 applications (with verification)
• Industrial temperature range systems

Procurement Notes

Verify the exact part number against official Renesas documentation, as '557MI' variants may differ from the standard '557M'. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component for designs requiring a dedicated 100 MHz PCIe clock source with HCSL signaling. Ensure the system accommodates the 3.3V supply voltage and 8-pin SOIC footprint. Verify that the 25 MHz reference frequency requirement aligns with the system's oscillator capabilities.

Part Context

This device belongs to the Renesas 557M series of clock generators. It is specifically engineered for PCI Express environments, offering a compact solution for generating precise clock signals required by high-speed interface standards.

Replacement Considerations

For PCIe Gen3 applications, consider the 5V41234. For Gen2 applications, verify compatibility with the 5V41064. Cross-reference specific pinouts and electrical characteristics when evaluating alternatives.
