USB2503A-HZH is a full speed USB Hub Controller that integrates the TUSB2040, TUSB2340, TUSB2340-1 and TUSB2340A standards into one device. This chip provides 4 downstream ports that can support speeds up to 480 Mb/s, 3.2 Gb/s, 2.5 Gb/s, 2.5 Gb/s and 2.0 Gb/s on each port. USB2503A-HZH meets the USB 2.0 specification and is compliant with USB3.0, USB3.1 and USB 3.2 specifications. It offers integrated features such as power cycling switching, soft start, port power control, over current protection and up stream port power control.

The USB2503A-HZH has a comprehensive set of features, which makes it suitable for use in a variety of applications. It can provide up to 12 ports of serial interface expansion, and supports data transfer rates up to 480 Mb/s. The chip also supports packet-receive and packet-transmit types, which can be used for a variety of application of internet protocol, such as GigaBit Ethernet, DKMS, and IDSN applications. The device is also USB 2.0 compliant, making it compatible with existing USB 2.0 standards.

The USB2503A-HZH has an integrated power management system that allows users to easily power cycle the device while the current is being adjusted. The power management system also allows users to monitor and control the power consumption of the device by setting the power switches in the required positions. This power management system is also used to increase the downstream port performance. It can be configured to disable the enable/disable pins on the downstream ports, or set the down stream port operating voltage to 1/3 or 2/3 of the full voltage.

In addition to the power management system, the USB2503A-HZH includes other features to help users efficiently manage their USB connection. The chip includes an on-chip programmable clock generator, which can be used to establish timing between the USB hub controller and the attached peripherals. This clock generator helps reduce the complexity of controlling the peripherals, as it allows users to configure the clock frequency for each peripheral. The chip also features a temperature sensing circuit, which helps to monitor the temperature levels of the USB hub controller and any connected peripherals.

The USB2503A-HZH also has an integrated over-current protection circuit. This circuit helps to protect the downstream port and any connected peripherals from damage due to sudden changes in current. It allows users to configure the over-current limit, and either the over-current limit or the over-current detect modes can be selected. In addition, the USB2503A-HZH also supports power cycle control, enabling users to alter the power supply configuration without having to disconnect the device.

The USB2503A-HZH is a powerful USB hub controller that provides users with an easy and efficient way to expand their device\'s serial interface capability. It supports transfer speeds up to 480 Mb/s, and integrates features such as power management, temperature sensing and over-current protection. Furthermore, it is compatible with USB 2.0, USB3.0, USB3.1 and USB 3.2 standards. It provides users with the perfect solution for an efficient and reliable serial interface expansion.
