---

The component is designed for multi-gigabit Ethernet applications and delivers 5GBASE-T, 2.5GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-Te support. With support for existing twisted pair cabling (Cat 5e/6/6a), the AQR114C-B0-I enables seamless infrastructure upgrades without replacing legacy cabling. Read on to discover the key features and applications of this powerful Ethernet physical layer (PHY). 

 

## **Key Features**

**Multi-Gigabit Speeds over Legacy Cabling**

The AQR114C-B0-I supports up to 5 Gbps over standard copper cabling, making it ideal for environments needing higher throughput without costly rewiring.

 

**Precision Time Protocol (PTP) with IEEE 1588v2**

With integrated 1588v2 PTP timestamping and Synchronous Ethernet (Sync-E) support, the AQR114C-B0-I ensures accurate clock signal synchronisation across devices on the PCB and precise extraction of timing information for latency-sensitive applications.

 

**MACsec Security**

Support for IEEE 802.1ae MAC Security (MACsec) with 256-bit (AES-256) key encryption provides secure end-to-end protection for data communications across networks. 

 

**Energy Efficient Ethernet (EEE)**

The AQR114C-B0-I lowers overall power consumption. EEE compliance reduces equipment operating costs and extends the lifespan of networking equipment.

 

**Thermal Management & Diagnostics**

On-chip thermal sensors with alarm and warning thresholds ensure safe deployment in thermally constrained environments. Advanced loopback and cable diagnostic tools facilitate network troubleshooting and optimisation.

 

**Industrial-Grade Performance**

The device operates across an extended industrial temperature range (−40°C to +108°C), making it suitable for deployment in rugged environments, edge computing applications, and outdoor installations.

 

## **Target Applications**

The AQR114C-B0-I is ideal for applications requiring reliable, secure, and high-speed Ethernet connectivity in compact or challenging environments. Use cases include: 

 

- Wireless Access Points (WAPs)
- Carrier Premises Equipment (CPE)
- Enterprise switches and routers
- Industrial and embedded systems
- Networked consumer devices
