PI6C49019AIEX

Overview

The PI6C49019AIEX is a single-circuit clock generator from Diodes Incorporated, designed for PCI Express applications. It features an integrated PLL and accepts LVCMOS or crystal inputs to generate HCSL or LVCMOS outputs. The device supports a maximum frequency of 125MHz with a 1:9 input-to-output ratio. It operates on a 3V to 3.6V supply voltage within a -40°C to +85°C temperature range. The component is housed in a 48-TSSOP surface-mount package.

Feature Summary

• Integrated PLL for clock generation
• Supports PCI Express main purpose
• 1:9 input-to-output ratio
• HCSL and LVCMOS output options

Applications

• PCI Express systems

Procurement Notes

Verify the specific suffix 'AIEX' against the manufacturer's official datasheet to confirm pinout, electrical characteristics, and RoHS compliance status. Ensure the 48-TSSOP package dimensions match the design constraints. Confirm availability and lead times through authorized distributors as stock levels vary.

Selection Notes

Select this component when a 1:9 fanout with integrated PLL is required for PCIe designs. Verify that the 125MHz maximum frequency meets system timing requirements. Ensure the PCB layout accommodates the 48-TSSOP footprint and that the 3V-3.6V supply rail is stable across the operating temperature range.

Part Context

This part belongs to the Diodes Incorporated clock generator family, specifically tailored for high-speed interface standards like PCI Express. It integrates frequency synthesis capabilities into a compact surface-mount package, reducing the need for external components compared to discrete solutions.

Replacement Considerations

Check for direct replacements within the same series that offer different output ratios or packages. Verify pin compatibility if substituting with other 48-pin clock generators. Ensure any alternative maintains the 125MHz frequency and 3V-3.6V supply specifications.
