Yes, the FSUSB42UMX is highly suitable for custom USB device designs¹²³⁴⁵. Here's why:
1. USB 2.0 Compatibility: The FSUSB42UMX is a high-speed USB 2.0 switch¹²³⁴⁵. It can switch between any combination of high-speed (480 Mbps) or Full-Speed (12 Mbps) sources¹²³⁴⁵. This makes it versatile for various USB applications, including custom designs.
2. Low On Capacitance and Resistance: The FSUSB42UMX features an extremely low on capacitance (CON) of 3.7 pF and a maximum on resistance of 6.5 Ohm¹²³⁴⁵. This helps in maintaining signal integrity during high-speed data transmission, which is crucial for USB applications.
3. Wide Bandwidth: The wide bandwidth (720 MHz) of this device exceeds the bandwidth needed to pass the third harmonic¹²³⁴⁵. This results in signals with minimum edge and phase distortion, ensuring high-quality data transmission in USB applications.
4. Power Efficiency: The FSUSB42UMX is designed to minimize current consumption, even when the control voltage applied to the SEL pin is lower than the supply voltage (VCC)¹²³⁴⁵. This feature is especially valuable in USB applications where power efficiency is a priority, such as in portable devices.
5. Connector Sharing: The FSUSB42UMX can be used for connector sharing in portable devices¹²³⁴⁵. This allows these devices to use a single USB port for multiple functions, saving space and reducing complexity.
In summary, the FSUSB42UMX's features such as USB 2.0 compatibility, low on capacitance, wide bandwidth, power efficiency, and ability for connector sharing make it highly suitable for a variety of custom USB device designs¹²³⁴⁵. However, it's always important to refer to the specific datasheet of the FSUSB42UMX for detailed information and recommendations related to design, layout, and development tools¹²³⁴⁵.
