USB3317C-GJ-TR

Drivers, Receivers, Transceivers Overview

The USB3317C-GJ-TR is a Hi-Speed USB 2.0 transceiver (PHY) utilizing the ULPI interface, designed for systems with a 26MHz reference clock. It supports 1.8V to 3.3V IO voltage and operates within an industrial temperature range of -40°C to +85°C. The device features an integrated low jitter PLL for 480MHz operation, an internal LDO regulator requiring a 2.2uF bypass capacitor, and full support for OTG protocols including HNP and SRP. It is housed in a lead-free RoHS compliant 25-pin VFBGA package measuring 3 x 3 x 0.88 mm.

Drivers, Receivers, Transceivers Feature Summary

• Supports USB On-The-Go (OTG) protocol with Host Negotiation Protocol (HNP) and Session Request Protocol (SRP).
• Includes an integrated low dropout regulator for power supply generation from battery or external sources.
• Features internal detection of ID pin resistance values for role determination.
• Provides internal 5V cable short-circuit protection on ID, DP, and DM lines.

Drivers, Receivers, Transceivers Applications

• Cell Phones
• Portable Media Players
• GPS Personal Navigation Devices
• External Hard Drives
• Digital Still and Video Cameras

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix GJ corresponds to the 25-pin VFBGA package configuration as documented in the official datasheet. Confirm that the component meets halogen maximum concentration values per IEC61249-2-21 standards. Ensure compatibility with the required 26MHz reference clock input before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this model when board space minimization is critical due to its compact 3x3mm footprint. Choose this variant over the QFN version if the target PCB layout accommodates ball grid array routing. Ensure the design supports the necessary 2.2uF bypass capacitor for the integrated LDO regulator functionality.

Drivers, Receivers, Transceivers Part Context

This component belongs to the USB3317 series of Hi-Speed USB transceivers manufactured by Microchip Technology. It shares core functional specifications with other variants in the family but differs in physical packaging. The series is designed to minimize interface pins while maintaining high-speed data transfer capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

USB3317C-CP-TR serves as a direct alternative offering identical electrical performance in a 24-pin QFN package. Verify PCB footprint compatibility when substituting between the VFBGA and QFN packages.

Drivers, Receivers, Transceivers FAQ

What is the function of the ID pin in non-OTG applications?

For non-OTG applications, the ID pin can be floated.

How does the device handle VBUS monitoring?

The USB3317 includes internal comparators for monitoring VBUS levels and supports driving external Vbus supplies or switches.

What is the minimum operating voltage for the integrated LDO?

The regulator dropout voltage is less than 100mV, allowing operation when VBAT drops to 3.1V.
