DRV1101U/2K5 Interface - Drivers, Receivers, Transceivers

Introduction

The DRV1101U/2K5 is a flexible, low-cost, high-performance fiber optic transceiver. It is a complete, integrated solution in a very small package. The DRV1101U/2K5 supports data transmission at up to 2.5Gbps over a single lane of fiber. It is designed to support a wide variety of serial data applications including storage area networks, gigabit Ethernet and Fibre Channel. The DRV1101U/2K5 is a transceiver with integrated clock and data recovery (CDR) capability, making it a perfect choice for high-speed fiber optic communication.

Application Field

The DRV1101U/2K5 is typically used for interfaces such as Fibre Channel, Gigabit Ethernet and FireWire. This transceiver is ideal for high-speed, long-distance applications such as those found in data centers and carrier networks. It can also be used in 1G and 2.5G ethernet and Fibre Channel switches and routers. The DRV1101U/2K5 is also well suited for data storage applications such as disk array and RAID systems.

The DRV1101U/2K5 is designed for applications requiring low power consumption. It operates at a power supply voltage of 3.3V and consumes very little power in idle mode. This makes it an ideal choice for use in rugged and remote environments where power consumption needs to be at a minimum.

Working Principle

The DRV1101U/2K5 encompasses a novel circuit design which enables it to perform both data transmission and reception at up to 2.5Gbps over a single lane of fiber. The transceiver is designed to accept NRZ data from the fiber at the transmitter and convert it to a non-return-to-zero (NRZ) format which is then sent to the receiver.

The DRV1101U/2K5 also includes clock and data recovery (CDR) circuit. The CDR circuit is used to recover the clock from the data and to ensure that the receiver is synchronized with the incoming data. The CDR circuit provides the necessary jitter suppression and wide acceptance of the data stream while ensuring that the receiver is properly synchronized.

The DRV1101U/2K5 also includes a built-in multi-channel equalization circuit. This circuit is used to reduce or eliminate inter-symbol interference (ISI) that may occur due to the limited bandwidth of the fiber. The equalizer helps to reduce the received signal to noise ratio and improves the bit error rate of the system.

The DRV1101U/2K5 also has the ability to perform open loop control for receiver equalization. This feature allows the transceiver to automatically adjust the equalizer gain and timing to match the received signal. The open loop control feature helps to reduce system complexity and results in improved performance.

The DRV1101U/2K5 includes a host of other features such as diagnostic monitoring, self-test mode, and an onboard voltage regulator. These features provide a comprehensive solution for demanding transceiver applications.

Conclusion

The DRV1101U/2K5 is the ideal transceiver for storage area networks, gigabit Ethernet and Fibre Channel applications. It is a complete, integrated solution that includes clock and data recovery, equalization, open loop control, and on-board voltage regulation. This unique combination of features make the DRV1101U/2K5 the perfect choice for high-speed, low power applications.
