Présentation
Description
The ASM1543 is a USB Type-C™ multiplexer (mux) switch designed by ASMedia Technology. It enables USB 3.1 Gen 2 (10Gbps) signal switching between two Type-C ports, supporting USB Power Delivery (PD) and Alternate Mode (Alt Mode) for DisplayPort or other protocols.
### Key Features:
- Dual-Channel 2:1 Mux – Switches high-speed signals (USB, DP) between two Type-C ports.
- Supports USB 3.1 Gen 2 (10Gbps) & USB 2.0 – Ensures high-speed data transfer.
- PD & Alt Mode Compatible – Enables video output (e.g., DP Alt Mode) and fast charging.
- Low Power Consumption – Optimized for power efficiency.
### Applications:
- Docks, hubs, and adapters with multiple Type-C ports.
- Laptops and tablets supporting USB-C multi-functionality.
The ASM1543 simplifies USB-C signal routing, making it essential for modern USB-C/Thunderbolt™ ecosystems.
