USB3319-GJ-TR

Drivers, Receivers, Transceivers Overview

The USB3319-GJ-TR is a Hi-Speed USB 2.0 transceiver (PHY) manufactured by Microchip Technology, housed in a 25-pin VFBGA package measuring 3 x 3 mm with a height of 0.88 mm. It operates on a 13MHz reference clock and supports a supply voltage range of 3.1V to 5.5V at the VBAT pin, generating an internal 3.3V rail. The device features a 1.8V ULPI interface compliant with Specification revision 1.1 as a Single Data Rate PHY. It includes an integrated low jitter PLL for 480MHz operation, an LDO regulator requiring a 2.2uF bypass capacitor, and ESD protection up to ±15kV. The industrial operating temperature range is -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix GJ corresponds to the 25-pin VFBGA package configuration. Confirm that the tape and reel quantity matches the standard 4000 pieces per reel specification. Ensure compliance with RoHS and halogen concentration values per IEC61249-2-21 requirements during procurement validation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when board space and interface pins must be minimized while requiring Hi-Speed USB connectivity. It is suitable for designs utilizing a 13MHz reference clock from the Link controller. Consider the integrated LDO and USB switch if external components for power regulation or signal routing are to be avoided.

Drivers, Receivers, Transceivers Part Context

This part belongs to the USB331x family of Hi-Speed USB transceivers designed for mobile and portable applications. It shares functional similarities with other members like the USB3317 but differs in package options and specific interface configurations. The GJ suffix specifically denotes the VFBGA packaging variant within this product line.
