Introduction

The TRS3223EIDB is a 3.3V, single-ended, full-duplex, low-power, low-voltage industrial-temperature transceiver. It can be used in mini-PCIe, PCIe and other Serial FFT applications. It is designed to provide reliable bi-directional communication in applications requiring the highest level of integration and compatibility with existing systems.

Application Field

The TRS3223EIDB is particularly suitable for applications in industrial automation and control, medical devices and other fields requiring high speed, low power and cost sensitive designs. It is widely used in applications such as:

• Surveillance
• Data acquisition
• Industrial control
• ROHS-Compliant Computing Platforms
• Low Power Embedded Automation
• Medical Imaging (MRI/PET/CT)
• Home Automation
• Intelligent Building Automation
• Packaging
• Industrial Imaging & Identification

The TRS3223EIDB is also widely used in wide range of industrial and Data/Telecommunication applications, such as

• Home networking
• LAN/WAN PC-card connections
• Bluetooth
• Wireless communications
• High-bandwidth switched Network Applications

Working Principle

The TRS3223EIDB is a full duplex transceiver, operating at 3.3V with a maximum data rate of 3.125MHz. It can also be adapted for applications requiring higher data rate using the selectable drive strength option. It is designed with a range of features to support most applications in industrial and data/telecommunication environment. The TRS3223EIDB is based on the enhanced asynchronous channel separation (ACS) feature. ACS is a special method of data error correction that is able to handle long data packets without any data errors. In ACS, the receiving circuitry uses a clock-recovery technique to sample each data packet, removing the jitter that can cause errors. The receiving circuitry also includes two-bit error detection and single-bit data scrambling, providing very low bit-error-rate performance.The digital side of the TRS3223EIDB also includes an Programmable 5 LE (Logical Enable) pins to provide additional flexibility in the configuration of the input/outputs. This is particularly useful in point-to-fiber applications requiring the user to configure the input/outputs according to a specific application requirement.The on-chip analog functions of the TRS3223EIDB include a built-in bias circuit for fiber optic receivers and transceivers. This feature helps to reduce system-level power consumption, by eliminating the need for additional external bias circuitry.

Conclusion

The TRS3223EIDB is an ideal solution for applications requiring high-speed, low-power and cost-sensitive designs. It is specifically designed to handle industrial and data/telecommunication applications. It’s enhanced asynchronous channel separation (ACS) feature offers very low bit-error-rate performance, and the programmable 5 LE (Logical Enable) pins provide additional flexibility in the configuration of the input/outputs. The on-chip analog functions also include a built-in bias circuit for fiber optic receivers and transceivers, thus reducing system-level power consumption.
