Introduction

NLX3G16DMUTCG (Dominant Transition Equalizer Receiver) is a logic buffer chip that is used in high-speed data transmission. It can realize transmission of data with 30Gbps rate on a 25Gbps Standard SerDes using less power, making it suitable for power-sensitive fast data transmission applications. This article will discuss how NLX3G16DMUTCG is used in logic applications, what its working principle is, as well as its benefits and drawbacks.

Application of NLX3G16DMUTCG

The NLX3G16DMUTCG is a device used in high-speed data transmission applications. It is an Integrated SerDes + LatticeSC receiver with Input VCXO and EIE-Offset calibration components. The device features a 0.8V supply voltage and works with a 25Gbps SerDes protocol. This chip is a logic buffer that helps transmit data at a lower power consumption rate at a 25 gigabit per second speed.The chip can be used in a variety of applications including Ethernet, optical communication, advanced memory buffering, system cards, embedded systems, high-speed networking systems, and data centers. It is used to convert parallel data into serial data, as well as to provide differential inputs and outputs to ensure better signal integrity. The NLX3G16DMUTCG is additionally compatible with NRZ and PAM4 signaling, which makes it suitable for a multitude of data throughputs.

Working Principle

The NLX3G16DMUTCG utilizes a dominant transition equalizer (DTEQ) receiver to enable high-speed transmissions on SerDes with 30Gbps rate. It has a 0.8V supply voltage and works with a standard SerDes of 25Gbps. It provides low jitter performance and can be used for both NRZ and PAM4 signaling interfaces.The DTEQ in this device works by adding a hysteresis margin to the SERDES receiver inputs. This provides immunity against false alarms/bit slips due to various types of crosstalk such as near-end crosstalk. The dominant transition equalizer (DTEQ) in the NLX3G16DMUTCG provides a larger eye opening and reduced jitter at 30Gbps.The DTEQ receiver has an on-chip voltage- controlled crystal oscillator (VCXO) and EIE-offset calibration logic. The VCXO is used to reduce jitter and helps maintain the frequency accuracy of the SERDES system. The EIE-offset calibration logic helps tracks the differential data-eye edges, providing decreased jitter and improve signal integrity.

Benefits

The NLX3G16DMUTCG has several benefits that make it suitable for powering high-speed data transmissions. The device features lower power consumption levels at a 25 gigabit per second speed, optimum signal integrity through better crosstalk-immunity, and reduced jitter at 30Gbps. These benefits make the NLX3G16DMUTCG a reliable solution for power sensitive fast data transmission applications.The chip also offers superior signal performance and improved jitter tolerance in systems that use VCXO for level shifting and EIE-offset calibration for Eye-opening and Signal Integrity. Additionally, the NLX3G16DMUTCG can be used in a variety of applications such as Ethernet, optical communication, advanced memory buffering, system cards, embedded systems, and data centers.

Drawbacks

Though NLX3G16DMUTCG has many benefits, it also has some drawbacks. It requires 3V CC supply, which limits its usage in low-voltage system boards. Additionally, the signal integrity levels, eye opening, and jitter levels are not ideal compared to devices that employ channel equalization or source-controlled receivers. The signal integrity performance is also dependent on the SERDES architecture and system board design.

Conclusion

NLX3G16DMUTCG is a logic buffer chip used in high-speed data transmission applications. It has a 0.8V supply voltage and works with a 25Gbps SerDes protocol. The chip utilizes a dominant transition equalizer (DTEQ) receiver to enable high-speed transmissions on SerDes with 30Gbps rate. The chip offers superior signal performance with improved jitter tolerance, low power consumption levels, and can be used in a variety of applications. Though the device does have some drawbacks, these are offset by the many benefits it provides for faster and more efficient data transmission.
