[Supply] KSZ8081RNAIA (Microchip) Single Chip 10/100 Base-T/TX Ethernet PHY Transceiver

Shenzhen Mingjiada Electronics Co., Ltd.——Long-term supply of Microchip KSZ8081RNAIA: High-performance, Low-power 10/100 Base-T/TX Ethernet PHY Transceiver

Product Overview 

The KSZ8081RNAIA is a highly integrated, single-port 10/100 Mbps Ethernet physical layer transceiver (PHY) from Microchip Technology. The KSZ8081RNAIA features an advanced, low-power design and supports the IEEE 802.3 standard, making it ideal for a wide range of applications such as industrial control, consumer electronics, IoT devices, and embedded networking systems. The KSZ8081RNAIA's excellent EMI/EMC performance and industrial-grade temperature range (-40°C to +85°C) make it ideal for harsh environment applications.

KSZ8081RNAIA Key Features and Benefits: 

1. High-Performance Network Connectivity 

The KSZ8081RNAIA supports 10BASE-T and 100BASE-TX Ethernet standards; 

Integrated adaptive equaliser, echo cancellation, and clock recovery ensure signal integrity; 

IEEE 802.3az Energy Efficient Ethernet (EEE) compliant with significant reduction in power consumption during idle time. IEEE 802.3az Energy Efficient Ethernet (EEE) compliant, significantly reducing power consumption when idle.

2. Low Power Design 

Operates at 78mW (100Mbps mode); 

Supports Power-Down Mode with standby current < 10μA; 

EEE mode further reduces power consumption by up to 50%. 3.

3. Interface Flexibility 

KSZ8081RNAIA provides RMII (Reduced Media Independent Interface) interface, which simplifies the connection with mainstream MAC controllers (e.g. ARM Cortex-M series); 

supports Auto-MDIX function, which automatically recognises direct or crossover cables without user intervention.

4. High Reliability and Immunity 

Built-in ESD protection (±8kV HBM) for enhanced system robustness; 

Excellent EMI/EMC performance, compliant with FCC, EN55022, etc.; 

Industrial temperature range: -40°C to +85°C. 

5. Simplified Design 

Single 3.3V power supply; 

Integrated termination resistors to reduce external components; 

Small 32-pin QFN (5×5 mm) package to reduce the need for external components; Small 32-pin QFN (5×5 mm) package to reduce the need for external components. Small 32-pin QFN (5 × 5 mm) package saves PCB space.

Typical application scenarios for the KSZ8081RNAIA: 

Industrial automation: PLC, HMI, industrial gateways
