PI6C557-06LEX

Overview

The PI6C557-06LEX is a clock generator manufactured by Diodes Incorporated, designed for PCI Express applications. It features one circuit with an input-to-output ratio of 2:4 and supports differential HCSL I/O. The device operates at a maximum frequency of 200 MHz within a supply voltage range of 3.135 V to 3.465 V. It functions in commercial temperatures from 0°C to 70°C and is housed in a 20-TSSOP surface-mount package.

Feature Summary

• PCI Express compliant clock generation
• 2:4 input-to-output ratio
• Differential HCSL I/O support
• 200 MHz maximum frequency

Applications

• PCI Express (PCIe) systems

Procurement Notes

Verify the operating temperature range against application requirements, as this component is rated for 0°C to 70°C. Confirm the 20-TSSOP package dimensions match the PCB layout. Ensure the 3.135 V to 3.465 V supply voltage aligns with system power rails before procurement.

Selection Notes

Select this model when a 2:4 fan-out ratio with differential HCSL outputs is required for PCIe designs. Note that it lacks internal PLL functionality. Verify that the commercial temperature range meets environmental needs, as industrial or automotive variants may require different part numbers.

Part Context

This component belongs to the Diodes Incorporated clock generator family targeting PCI Express standards. It provides signal distribution capabilities using HCSL technology. The 20-TSSOP package facilitates surface-mount integration into high-speed digital circuits requiring precise timing signals.

Replacement Considerations

Check for direct substitutes with identical 2:4 ratios and HCSL outputs. Verify pin compatibility and electrical specifications if considering alternative manufacturers.
