ON Semiconductor FSA644BUCX - High-Speed USB 2.0 Switch

The FSA644BUCX from ON Semiconductor is a versatile high-speed USB 2.0 (480 Mbps) switch specifically designed to handle multiple USB signals through a single device. This advanced switch is an ideal solution for USB multiplexing that requires low on-capacitance (C<sub>on) and low on-resistance (R<sub>on) to minimize signal distortion and attenuation in applications such as mobile phones, digital cameras, and notebooks.

Key Features:

• USB 2.0 Compliance: Ensures compatibility with high-speed data transfer rates of up to 480 Mbps.
• Low Power Consumption: Designed for battery-powered devices where power conservation is critical.
• High Bandwidth: Offers a wide bandwidth to maintain signal integrity for high-speed data transmission.
• Bi-Directional Switching: Capable of switching USB 2.0 signals from a common D+/D- pair to two different destinations or vice versa.
• Low Crosstalk: Minimizes interference between channels to ensure reliable data transfer.
• ESD Protection: Integrated electrostatic discharge protection to safeguard against voltage spikes.

Applications:

• Smartphones and Tablets
• Notebook and Desktop Computers
• Portable Media Players
• Digital Cameras and Camcorders
• USB Peripheral Devices
• Docking Stations

With its compact UMLP (Ultra Micro Lead Package) footprint, the FSA644BUCX occupies minimal space on the PCB, making it an excellent choice for space-constrained designs. The switch's low crosstalk and high isolation ensure that signal integrity is maintained, even in complex multi-port scenarios. Moreover, the FSA644BUCX is designed to work seamlessly with both 1.8V and 2.5V control logic levels, providing flexibility in various design architectures.

Whether you're designing a new mobile device that requires reliable USB switching or upgrading an existing product, the FSA644BUCX offers the performance and reliability that ON Semiconductor is known for. Its robust feature set and compliance with USB 2.0 standards make it a prime choice for designers looking to enhance their USB interface capabilities.
