Microchip Technology USB3317-GJ-TR USB Transceiver

The USB3317-GJ-TR from Microchip Technology is a highly integrated USB 2.0 Transceiver that operates at high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps). Designed for portable electronic devices, this transceiver is a perfect solution for applications requiring USB connectivity with minimal space usage and power consumption. The USB3317-GJ-TR offers a flexible interface with a ULPI (UTMI+ Low Pin Interface) that allows for direct connection to a ULPI compliant Link layer.

With its small 4x4 mm QFN-24 package, the USB3317-GJ-TR is optimized for compact designs, making it an ideal choice for mobile phones, digital cameras, and other space-constrained USB peripheral devices. This transceiver is also available in a tape and reel format, ensuring it is ready for automated assembly processes, which is denoted by the 'TR' suffix in its part number.

The device supports a wide range of core voltages from 1.8V to 3.3V, which provides designers with the flexibility to match the transceiver's power requirements with the system's power scheme. The USB3317-GJ-TR also features an integrated 24MHz crystal oscillator driver, removing the need for an external crystal and further reducing the bill of materials and board space.

Key features of the USB3317-GJ-TR include:

• USB-IF High-Speed certified
• Integrated pull-up and pull-down resistors
• Support for both Host and Peripheral modes
• Low power consumption with an advanced power management system
• Over-current and ESD protection circuits to enhance system reliability
• Automatic squelch circuit to detect disconnect events

The USB3317-GJ-TR transceiver is a testament to Microchip Technology's commitment to providing advanced connectivity solutions that meet the needs of modern portable devices. Its robust feature set, combined with its small footprint, makes it an excellent choice for designers looking to incorporate USB functionality into their next-generation products.
