DSC557-0333FI0

Overview

The DSC557-0333FI0 is a two-output PCI Express clock generator from the DSC557 series, manufactured by Microchip Technology. It utilizes silicon MEMS technology to generate a 100 MHz differential clock signal without requiring an external crystal. The device supports LVDS output format and operates within a supply voltage range of 2.25V to 3.6V. It complies with PCIe Gen1 through Gen4 common clock specifications and features an integrated PLL. The component is housed in a 14-VFQFN package with an exposed pad and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Two-output PCIe clock generator compliant with Gen1/2/3/4 specifications
• Integrated MEMS resonator eliminates the need for an external 25 MHz crystal
• LVDS output format with 100 MHz frequency
• Operating temperature range of -40°C to +85°C

Applications

• PCI Express (PCIe) systems
• Communications and networking equipment
• Storage solutions such as SAN and NAS

Procurement Notes

Verify the specific ordering suffix against the manufacturer's product identification system to confirm output formats, temperature grade, and packaging media. Ensure compatibility with the target application's voltage and interface requirements before procurement.

Selection Notes

Select this model for applications requiring dual LVDS outputs at 100 MHz within the industrial temperature range. Consider alternative suffixes if HCSL or LVCMOS outputs are needed, or if extended industrial (-40°C to +105°C) or commercial (-20°C to +70°C) temperature ranges are required.

Part Context

This part belongs to the DSC557-03 family of two-output PCIe clock generators. The family offers various output combinations including HCSL, LVDS, and LVCMOS across different temperature grades and packaging options.

Replacement Considerations

Direct replacements within the same family include variants with different output formats or temperature ratings, such as DSC557-0344FI0 for HCSL outputs in the same temperature range.
