The chip also consumes low power, which is beneficial for battery-powered devices. Its compatibility with multiple USB devices and its low cost has made it a popular choice for USB hub applications.

FE1.1S chip requires a single 3.3V power supply and can operate over a temperature range of -40°C to +85°C. To implement the FE1.1S chip in a PCB design, there are a few things to consider:

Power Supply: The FE1.1S chip requires a stable 3.3V power supply. It is important to ensure that the power supply is capable of providing enough current to power the chip and any connected USB devices.
Layout: The layout of the FE1.1S chip on the PCB should be carefully designed to ensure proper signal integrity and minimize noise. The USB traces should be kept as short as possible and should be routed away from other high-speed signals.
Decoupling Capacitors: Decoupling capacitors should be placed as close as possible to the power supply pins of the FE1.1S chip to ensure stable operation and minimize noise.
ESD Protection: To protect the FE1.1S chip from electrostatic discharge (ESD) damage, it is recommended to add ESD protection devices to the USB data lines.
USB Connectors: The USB connectors should be carefully selected to ensure compatibility with the FE1.1S chip and the connected USB devices. It is recommended to use shielded connectors to minimize noise and EMI.
Grounding: Proper grounding is important to ensure proper operation of the FE1.1S chip and any connected USB devices. It is recommended to use a solid ground plane and to connect the ground pins of the USB connectors directly to the ground plane.

To design a product that uses FE1.1S chip in a PCB, it is important to consider the power supply, layout, decoupling capacitors, ESD protection, USB connectors, and grounding. Careful design and attention to these details can help ensure proper operation and compatibility with a wide range of USB devices.
