HX5401NL Electrical Performance Overview

HX5401NL is designed for gigabit Ethernet performance with the electrical characteristics required by modern LAN interfaces. According to the provided parameters, the part offers:

• Insertion loss: 1.5 dB max from 1–100 MHz
• Return loss: optimized across 1–100 MHz
• Common-mode rejection ratio (CMMR): strong suppression across key frequency ranges
• Crosstalk: controlled for multi-channel signal integrity
• PoE power handling: 4P PoE up to 30W max

These values are important because PoE LAN transformers must do more than pass data. They must maintain signal quality while managing power delivery and EMI performance in a compact Ethernet interface.

Detailed Electrical Parameters

1. Insertion Loss

1–100 MHz: 1.5 dB max

Low insertion loss helps preserve signal quality in 1000BASE-T designs. This is especially important in Ethernet systems where margin is limited and link stability depends on clean transmission through the magnetics stage.

2. Return Loss

• 1–30 MHz: -18 dB min
• 40 MHz: -16 dB min
• 50 MHz: -14 dB min
• 60–80 MHz: -11 dB min
• 100 MHz: -10 dB min

Return loss indicates how well the transformer maintains impedance matching across the operating band. Better return loss supports link reliability and reduces reflections that can degrade Ethernet performance.

3. CMMR

• 30–60 MHz: -32 dB min
• 80–100 MHz: -25 dB min
• 125 MHz: -19 dB min

​

Common-mode rejection is critical in Ethernet magnetics because it helps suppress noise that can affect signal integrity, especially in noisy industrial or high-density networking environments.

4. Crosstalk

• 30 MHz: -44 dB min
• 60 MHz: -37 dB min
• 100 MHz: -33 dB min

​

Low crosstalk is important in quad-port designs because multiple channels are placed close together on the PCB. HX5401NL is intended for designs that need stable performance across all ports.

Why the BGA Mounting Style Matters

HX5401NL uses a BGA bump grid array mounting style, which is valuable for compact PCB layouts and automated assembly processes. For engineers, this means:

• Efficient board integration
• Good fit for high-density designs
• Suitable for modern SMT manufacturing
• Compact footprint for networking equipment

This packaging approach is often preferred where layout space is limited and the product must maintain reliable electrical performance.

What Design Teams Should Check Before Choosing HX5401NL

Before finalizing HX5401NL in your BOM, confirm the following:

• Your application is 1000BASE-T, not 10/100 only
• Your PCB supports the BGA mounting style
• Your PoE requirement is within 30W max
• The PHY vendor supports compatible magnetics characteristics
• The thermal range of -40°C to +85°C is sufficient
• The return loss, insertion loss, and crosstalk fit your system margin

These checks help reduce redesign risk and improve first-pass success in Ethernet hardware development.
