USB3450-FZG

Drivers, Receivers, Transceivers Overview

The USB3450-FZG is a standalone Hi-Speed USB Physical Layer Transceiver (PHY) manufactured by Microchip Technology. It features a UTMI+ interface compliant with Specification Rev. 1.0, supporting HS, FS, and LS data rates. The device operates from a single 3.3V supply via internal 1.8V regulators and includes an integrated 24MHz crystal oscillator or external clock input. Key electrical parameters include a typical unconfigured current of 55mA and a suspend current of 83uA. It provides low latency reception with a maximum of 43 Hi-Speed clocks and supports host or device functionality within a 40-pin QFN package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix -FZG against official documentation to confirm package type and temperature range. Ensure the ordering information matches the exact datasheet revision required for your design. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dedicated PHY is required for SOC, ASIC, or FPGA designs. It is suitable for applications needing bus-powered operation due to its low unconfigured current. Verify that the system design can accommodate the 40-pin QFN footprint and meets the thermal requirements for the commercial operating temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the USB3450 series of Hi-Speed USB transceivers. It is designed to simplify USB integration by providing a complete analog PHY block. The device allows designers to add USB connectivity without implementing complex analog circuits internally within their main controller chip.

Drivers, Receivers, Transceivers Replacement Considerations

Check for updated revisions of the USB3450 series. Verify pin compatibility if considering alternative PHYs. Ensure any substitute maintains UTMI+ Level 3 support and similar power consumption characteristics for direct replacement in existing designs.
