557MI-01LF

Overview

The Renesas 557MI-01LF is a single-output clock generator designed for PCI Express applications. It accepts a 25 MHz input and generates a 100 MHz output signal. The device operates on a 3.3 V supply with a typical current consumption of 55 mA. It is housed in an 8-pin SOIC package and supports HCSL or LVDS output levels. The component functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Single differential output at 100 MHz
• Supports HCSL and LVDS signaling levels
• 25 MHz crystal input frequency
• 8-pin SOIC surface-mount package

Applications

• PCI Express card clock sources
• Embedded systems requiring low jitter clocks
• PC motherboard clock distribution

Procurement Notes

Verify RoHS compliance status through official datasheets, as packaging options may vary between lead-free and green compliant versions. Confirm the specific suffix requirements for your manufacturing process. Check for end-of-life notifications or discontinuance alerts from Renesas Electronics before finalizing procurement plans.

Selection Notes

Select this component when a single 100 MHz differential clock source is required for PCIe Gen1 interfaces. Ensure the design accommodates the 8-pin SOIC footprint. Verify that the 3.3 V supply voltage aligns with the system power architecture. Consider thermal dissipation capabilities within the specified 0°C to +70°C operating range.

Part Context

This part belongs to the 557M series of clock generators. It serves as a foundational timing solution for legacy PCI Express implementations. Related models in the family offer multiple outputs or support higher generation standards such as PCIe Gen2 or Gen3.

Replacement Considerations

Direct substitutes include other single-output 100 MHz PCIe clock generators from IDT/Renesas. Verify pin compatibility and output signaling levels (HCSL/LVDS) when cross-referencing with alternative components.
