The DS99R124AQSQ/NOPB is an advanced serializer/deserializer (SERDES) device from Texas Instruments. It features adjustable linear transceiver with integrated transmitter pre-emphasis, Rx equalization, and auto-calibration for optimized performance over a wide range of trace lengths and materials. The SERDES can supply up to 10Gb/s of data throughput, making it an ideal solution for data intensive applications.

Application Field

The DS99R124AQSQ/NOPB SERDES is designed for mission-critical applications, such as datacenters, enterprise networks, and other applications requiring very high speed data transmission. It supports a wide range of trace lengths, allowing it to be used in many different system designs. It is also designed to be used in multi-master and multi-slave configurations, providing a cost-effective solution to complex communication topologies. Furthermore, its auto-calibration feature makes it easy to set up and maintain, helping to decrease the time needed to configure the system and reduce downtime.

Working Principle

The DS99R124AQSQ/NOPB SERDES works on the principle of low-level encoding and low-voltage source synchronization (LVSS). Low-level encoding is used to convert an incoming data stream into a bitstream, which is then transmitted over the connection. On the receiving end, LVSS re-synchronizes the received bitstream to reduce timing-skews, allowing the receiver to accurately identify the bitstream pattern and convert it back into the original data stream. This principle is particularly useful for data intensive applications such as high definition video streaming or large file transfers.

The SERDES also features a programmable transmitter pre-emphasis, Rx equalization, and integrated power management. In addition, the device uses a differential output buffer to reduce jitter and noise, as well as an adaptive equalizer to compensate for trace length variations. This ensures robust data transmission over a wide range of distances.

Conclusion

The DS99R124AQSQ/NOPB Serializer/Deserializer from Texas Instruments is a powerful and versatile product designed to improve data transmission performance in mission-critical applications. Its advanced features and integrated power management make it ideal for a variety of applications requiring very high speed data rates. The SERDES is also highly reliable, with a wide range of trace lengths and auto-calibrations making it easy to set up and maintain.
