회사 블로그 Supply: TUSB544 USB 3.1 Gen 1 DP 1.4 Adapter Driver, Laptop Dock Interface Chip

Shenzhen Mingjiada Electronics Co., Ltd. is a professional spot trader, supplier, and inventory recycler of electronic components. We have long supplied Texas Instruments (TI) interface signal chips and maintain a stable supply of genuine TUSB544 chips in stock. We support sample orders, small-batch orders, and large-volume orders, and also handle the recycling of factory surplus, obsolete inventory, goods returned to the port, and electronic components seized by customs.

The TUSB544 is a USB Type-C Alternate Mode multi-protocol linear redriver that supports data transfer rates up to 8.1 Gbps. It is a protocol-agnostic, reversible 4-channel signal conditioning chip compatible with USB 3.1 Gen 1 and DisplayPort 1.4 Alternate Mode. It is a commonly used signal conditioning chip in Type-C docks, laptops, tablets, and active USB Type-C cable solutions.

The chip features built-in multi-stage linear equalization, with equalization capability reaching up to 11 dB at 4.05 GHz. It compensates for signal loss and intersymbol interference (ISI) caused by PCB traces and high-speed cables, thereby extending the transmission distance of high-speed signals; All four channels support bidirectional configuration. Paired with an SBU cross-multiplexer, it supports both GPIO and I²C configuration methods. It features built-in hot-swap protection and intelligent power management, achieving low-power control by monitoring USB power status and DP link training. Powered by a single 3.3V supply, it is simple to use and highly stable.
