Texas Instruments TUSB217RGYTQ1 USB 2.0 High-Speed Signal Conditioner

The TUSB217RGYTQ1 from Texas Instruments is a high-speed USB 2.0 signal conditioner designed to enhance signal quality by performing pre-emphasis on the transmitted signal and equalization on the received signal. This device is tailored for use in automotive and industrial applications where long cable runs or noisy environments can degrade signal integrity, leading to unreliable communication and data transfer.

With a focus on performance and reliability, the TUSB217RGYTQ1 supports data rates up to 480 Mbps and is compatible with both full-speed (12 Mbps) and low-speed (1.5 Mbps) data rates. This makes it an ideal solution for a wide range of USB-based applications including in-car entertainment systems, diagnostic ports, and connectivity modules.

The TUSB217RGYTQ1 is equipped with an adaptive equalizer that automatically adjusts to the optimal level of equalization for the cable length used, thus simplifying design and reducing the need for manual system tuning. Additionally, the built-in pre-emphasis feature helps to overcome signal loss at the transmitter, ensuring that the signal integrity is maintained over extended cable distances.

This signal conditioner is housed in a compact 16-pin QFN package, which not only saves space on the PCB but also provides robustness for harsh automotive environments. It operates over the standard automotive temperature range of -40°C to +85°C, ensuring reliable performance under varying conditions.

Key features of the TUSB217RGYTQ1 include:

• Support for USB 2.0 High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) operation.
• Adaptive equalization for optimal performance with various cable lengths.
• Integrated pre-emphasis to boost signal strength at the transmitter.
• Compliance with USB-IF Battery Charging Specification Rev 1.2.
• Enhanced Electrostatic Discharge (ESD) protection.
• Compact 16-pin QFN package suitable for space-constrained applications.

The TUSB217RGYTQ1 is a robust and versatile USB 2.0 signal conditioner that ensures high-speed data integrity for demanding automotive and industrial USB applications.
