The device is an ultra-low-power, single-channel SerDes with an integrated clock-data recovery circuit. Supporting typical data rates of up to 4Gbps, it is ideal for a number of communication interface applications. This document is intended to provide an overview of DS92LV2412SQX/NOPB, its applications and working principles.

Applications

The DS92LV2412SQX/NOPB is a highly integrated device suitable for a variety of applications. It can be used to interface different buses and signals in a variety of high-speed communication systems. The SerDes is also well-suited for applications requiring large amount of data transfer, such as video, imaging, data storage, backplane, InfiniBand, and Ethernet. This device can even be used in automotive systems, such as in-car entertainment, rear view mirrors with LCD display, and driver assistance systems.

The device can be used to transfer clock, control and data information over common channels. It can be used as an interface between two buses, such as a processor bus and a data bus. It can also be used to interface different types of signalling, such as differential and single-ended signalling. Additionally, the SerDes can be used in bidirectional applications.

Working Principle

The DS92LV2412SQX/NOPB is an ultra-low-power, single-channel SerDes with an integrated clock-data recovery circuit. The device supports typical data rates of up to 4Gbps. The SerDes operates in a serializer or parallel-to-serial conversion mode, while the integrated clock-data recovery circuit can recover the clock and data from the serial data stream. The SerDes has an on-chip parallel data interface, which supports input and output data rates of up to 4 Gbps.

The integrated clock-data recovery circuit is self-calibrating and utilizes an active non-return-to-zero (NRZ) data interface. This allows the device to accept data input in both NRZ and non-NRZ formats. The integrated clock-data recovery circuit is capable of adaptive equalization, which improves the total link performance. The device also features an on-chip jitter reduction circuit, which further improves system performance. The device supports a variety of jitter specifications, which helps to ensure reliable synchronization of the transferred data.

In addition to these features, the DS92LV2412SQX/NOPB has integrated error detection and correction circuitry. The device features an on-board status output (CDR lock) to indicate a valid data rate. This allows the system to detect a loss of signal or a data rate mismatch. The device also features an integrated phase-locked loop (PLL) for enhanced clock stability and system performance.

Conclusion

The DS92LV2412SQX/NOPB is a high-speed single-channel SerDes with an integrated clock-data recovery circuit. It is ideal for a number of communication interface applications, including data storage, backplane, InfiniBand, Ethernet, video, imaging, and automotive systems. The device supports typical data rates of up to 4Gbps and helps to ensure reliable synchronization of the transferred data. Additionally, the device features an on-board PLL, jitter reduction circuit, and error detection and correction circuitry for enhanced system performance.
