The TUSB522PRGER is a high-performance, adaptive equalization USB 3.2 Gen 1 dual-channel redriver from Texas Instruments (TI). This advanced integrated circuit is designed to enhance signal quality by performing receive equalization on the deteriorated input signal, followed by transmit de-emphasis, maximizing system link performance. It is an ideal solution for applications where signal integrity may be compromised due to long PCB traces, cables, or other challenging transmission media.

Key Features

• Dual-Channel Redriver: The TUSB522PRGER features two bidirectional channels, supporting both downstream and upstream traffic, which is essential for versatile USB 3.2 Gen 1 applications.
• Adaptive Equalization: This product incorporates adaptive equalization technology, which automatically adjusts to the optimal level to compensate for inter-symbol interference (ISI) and to restore signal integrity.
• Transmit De-Emphasis: The device provides programmable transmit de-emphasis, allowing for the reduction of transmission errors by compensating for channel losses.
• Low Power Consumption: The TUSB522PRGER is designed with power efficiency in mind, maintaining low power consumption to meet the needs of power-sensitive applications.
• Small Form Factor: Packaged in a small, 3 mm x 4.5 mm, 24-pin QFN package, the TUSB522PRGER saves valuable board space, making it suitable for compact systems.
