The PI7C9X1170BZDEX is an interface controller that provides a bridge between a devices digital and analog worlds, allowing for connected digital devices to easily interact with analog devices. It also builds a separate communication channel for each device, which means more resources are available to various tasks and more data can be transferred in both directions. This makes it ideal for applications where data needs to be exchanged between different systems.

Overview

The PI7C9X1170BZDEX is an integrated single-chip USB 3.0-to-dual-mode-Line Device Controller, compliant with the USB 3.0 specification for device-level control support. It facilitates communication between 28nm-based PC systems and their connected device, which are mostly portable devices such as audio/video players. It supports both USB 2.0 and USB 3.0 communication as well as Enhanced Host Controller Interface (EHCI) and xHCI controller stacks. It enables communication between the systems and their connected device via a hub-based architecture, allowing a single host to manage multiple peripheral devices.

The PI7C9X1170BZDEX is based on an advanced dual-mode architecture which builds a separate communication channel for each connected device. This allows for more data to be transferred in both directions, making it easier for the device to transfer data back to the host. It also allows for a higher bandwidth, making it suitable for applications that require faster transfer speeds.

Features

The PI7C9X1170BZDEX is designed with a variety of features to support applications with USB 3.0 interfaces. It is capable of a maximum of 5 Gbps USB 3.0 transfer rate. It supports up to eight downstream endpoints, allowing for the connection of multiple peripherals. It also has an embedded programmable USB dual-mode block diagram (i.e. Data Link Layer), which configures the system for optimal performance. It is compliant with the USB 3.0 specification for device-level control support, meaning that it can be used with a wide range of USB 3.0 devices.

The PI7C9X1170BZDEX also has several power saving features which help to reduce power consumption and improve battery life. It is capable of dynamically switching between full-power and low-power state as required, as well as supports power-saving modes such as Link Power Management (LPM), USB Suspend, and Selective Suspend. Additionally, it supports multiple clock gating schemes, power down and reset, to minimize power dissipation while the device is idle.

Application Field and Working Principle

The PI7C9X1170BZDEX is designed for applications where data needs to be exchanged between different systems, such as audio/video players, home media systems, automotive infotainment systems, and embedded systems. It is also suitable for applications where a low power solution is required. It is typically used in applications where the data rate and power consumption are both important factors.

The PI7C9X1170BZDEX operates by providing a bridge between the solid and analog worlds. When a device with a USB 3.0 interface is connected, it will establish the connection by establishing the link between the PC\'s PCIE bus and the USB device. The embedded programmable USB dual-mode block diagram will then configure the system for optimal performance. The device then creates a separate communication channel, allowing for faster data transfer rates and power savings.

Advantages and Disadvantages

The PI7C9X1170BZDEX has a number of advantages that make it a suitable choice for applications that require data to be exchanged between different systems. It allows for quick, easy communication between PC systems and their connected devices. It is also compliant with the USB 3.0 specification for device-level control support, which means it can be used with a wide range of devices. Additionally, it has built-in power saving features, requiring less energy for operation. Finally, it is capable of dynamic power saving and allows for USB suspend and selective suspend.

One of the drawbacks of the PI7C9X1170BZDEX is its limited number of endpoints. It is only capable of supporting up to eight downstream endpoints, meaning that multiple peripherals cannot be connected if more than eight are required. Additionally, it cannot support connections with multiple hosts, meaning that each connection must be established individually.

Conclusion

The PI7C9X1170BZDEX is an interface controller designed to facilitate communication between PC systems and their connected devices. It is compliant with the USB 3.0 specification for device-level control support, allowing it to be used with a wide range of devices. It has an embedded programmable USB dual-mode block diagram for optimal performance, as well as supports dynamic power saving with USB suspend and selective suspend. It is well-suited for applications where data needs to be exchanged between different systems, though its limited number of endpoints is a drawback.
