DSA557-0334FL1TVAO

Overview

The Microchip Technology DSA557-0334FL1TVAO is an automotive-grade, crystal-less PCI Express clock generator utilizing silicon MEMS technology. It provides two differential 100MHz outputs with HCSL or LVDS formats. The device operates within a supply voltage range of 2.25V to 3.63V and supports temperatures from -40°C to +105°C. Packaged in a compact 14-VFQFN (2.5x3.2mm) with an exposed pad, it eliminates the need for external crystals, offering high reliability and low jitter suitable for PCIe Gen1/2/3/4 applications.

Feature Summary

Automotive Grade AEC-Q100 qualified for -40°C to +105°C operation
Silicon MEMS technology eliminates external 25MHz crystal requirements
Dual 100MHz differential outputs supporting HCSL and LVDS formats
Compact 14-pin VQFN package (2.5x3.2mm) reduces board space

Applications

PCI Express compliant systems
Automotive infotainment systems
Automotive ADAS applications
On-board networking equipment

Procurement Notes

Verify the specific suffix 'TVAO' against official Microchip documentation to confirm tape-and-reel packaging and any material composition details. Ensure the ordering code matches the required output format and temperature grade specifications before procurement.

Selection Notes

Select this component for designs requiring dual differential clocks without external resonators. Confirm that the system power supply remains within the 2.25V to 3.63V range. Verify that the 14-VFQFN footprint aligns with the PCB layout constraints and thermal requirements for the exposed pad.

Part Context

This part belongs to the DSA557-03 series, which offers two-output configurations. Other variants in the family include the DSA557-04 (three outputs) and DSA557-05 (four outputs), typically housed in 20-pin packages. The DSC557 series represents the commercial/industrial counterpart to this automotive-grade device.

Replacement Considerations

Direct replacements include other DSA557-03 variants with different suffixes for packaging or minor parameter adjustments. Cross-series substitution with DSC557-03 requires verification of temperature range compliance.
