**HMC967LP4E: A High-Performance 24 Gbps Clock and Data Recovery IC for Next-Generation Optical Networks**

The relentless growth of global data traffic, driven by cloud computing, 5G, and streaming services, is pushing the physical limits of optical communication networks. To meet the escalating demand for bandwidth, next-generation systems require components that offer not only higher data rates but also superior signal integrity. The **HMC967LP4E** stands at the forefront of this evolution as a **high-performance 24 Gbps Clock and Data Recovery (CDR)** integrated circuit, engineered to address the critical challenges of modern optical interconnect applications.

At the heart of any high-speed serial data link, the CDR performs the essential function of extracting a clean clock signal from an input data stream that is often degraded by jitter, attenuation, and noise. The HMC967LP4E excels in this role, featuring an exceptionally low jitter generation of **under 100 fs RMS** and a high input sensitivity capable of operating with severely attenuated signals. This ensures robust performance even over long reaches of fiber or backplane traces, significantly reducing the bit error rate (BER) and enhancing the overall link budget.

A key architectural strength of this IC is its **fully integrated loop filter**, which eliminates the need for external components, simplifies board design, and reduces the overall system footprint. The device supports both **continuous and burst-mode operation**, making it exceptionally versatile for a range of applications from fixed telecom infrastructure to packet-based access networks like 25G-EPON. Its ability to quickly achieve phase lock is critical for maintaining efficiency in burst-mode systems where data packets arrive asynchronously.

Furthermore, the HMC967LP4E is designed for seamless integration within larger systems. It offers multiple output types, including CML (Current Mode Logic) and LVDS (Low-Voltage Differential Signaling), providing flexibility for interfacing with various host devices such as FPGAs or DSPs. Its programmable features, such as output amplitude control and loss-of-lock (LOL) indicators, give system designers greater control and diagnostic capabilities, enabling more reliable and manageable network equipment.

Deployed in 100G/200G/400G optical transceivers, line cards, and active optical cables (AOCs), the HMC967LP4E provides the foundational timing and signal conditioning necessary for the next leap in data center and telecommunications networking. Its performance directly enables the dense, high-speed interconnects that form the backbone of the modern internet.

**ICGOOODFIND:** The HMC967LP4E is a pivotal component for advanced optical systems, delivering **industry-leading jitter performance**, **high sensitivity**, and **operational flexibility** in a single package. Its integration simplifies design and empowers the development of faster, more reliable next-generation networks.
