TS3USB31RSER Typical application Circuitry

TS3USB31RSER

The TS3USB31RSER is a significant component in Texas Instruments' TS3 series, specifically engineered as a high-speed USB 2.0 (480 Mbps) single-channel multiplexer/demultiplexer switch. This device is designed to facilitate efficient switching between two USB signals, making it an ideal choice for applications like peripheral sharing in computers and docking stations, where USB signal routing is necessary.

1. Power Supply Connection: For best results, the TS3USB31RSER needs a steady power source. It typically operates with a single power source, with the supply voltage connected to the VCC pin. This voltage must be within the specified range as per the device's datasheet. A reliable reference for the device's operations is provided by the ground pin (GND), which is linked to the system's ground.

2. USB Signal Switching Configuration: The device features a common signal port (D+/D-), two signal pairs for input/output (1D+/1D- and 2D+/2D-), and a select input (SEL). The common port is used for the USB signal that needs to be routed, and depending on the logic level applied to the SEL pin, the TS3USB31RSER connects the common port to either the 1D+/1D- pair or the 2D+/2D- pair.

3. Control Input for Selecting Signal Paths: The SEL pin acts as a control input for the switch. Applying a high or low logic level to this pin determines which set of D+/D- lines are connected to the common D+/D- lines, enabling the switch to route the USB signals between two different paths.

4. Design for High-Speed Signal Integrity: The TS3USB31RSER is designed to maintain signal integrity at high USB 2.0 speeds. When integrating this device into a system, it is essential to ensure that the PCB layout minimizes signal degradation. This involves careful trace routing, impedance matching, and maintaining the integrity of the differential signal pairs.

5. ESD Protection and Handling: Integrated electrostatic discharge (ESD) protection is included with the gadget. Despite this, it is advisable to handle the TS3USB31RSER with appropriate ESD precautions to prevent damage during installation or handling.

6. Thermal Considerations: While the TS3USB31RSER is not known for significant heat generation, it is still important to consider thermal management in the overall design, especially if used in a tightly packed electronic environment.

7. Optimized PCB Layout for Enhanced Performance: The performance of the TS3USB31RSER is heavily dependent on the PCB layout. Ensuring minimal trace lengths, proper grounding, and shielding, particularly for the high-speed differential lines, is crucial for maintaining signal quality and the effective functioning of the USB switch.

In summary, the TS3USB31RSER is a versatile USB 2.0 switch that plays a crucial role in applications requiring the routing of USB signals between different paths. Effective implementation involves careful consideration of power supply connections, signal switching configuration, control input management, high-speed signal integrity, ESD safety, thermal management, and strategic PCB layout. These factors are key to leveraging the full potential of the TS3USB31RSER in various USB signal routing applications.
