FIDO2100PLQ128IR0

Specialized Overview

The FIDO2100PLQ128IR0 is a managed, 3-port Ethernet switch from the Innovasic fido family. It supports IEEE-1588 and Device Level Ring (DLR) protocols for industrial applications. The device features two external ports and one internal port connecting to a host CPU. It operates at 10/100Mbps with full wire-speed, non-blocking switching logic. The component provides low latency via cut-through forwarding and includes hardware assist for IEEE 1588 Ordinary and Transparent clocks. It supports DLR media redundancy and functions within an industrial temperature range of -40°C to +85°C.

Specialized Feature Summary

• Supports IEEE 802.3 MAC compliance with full duplex flow control using PAUSE frames and half duplex back pressure.
• Provides hardware-assisted IEEE 1588 V2 functionality for both ordinary clock and end-to-end transparent clock operations.
• Enables Device Level Ring (DLR) protocol support for media redundancy with automatic topology detection.
• Utilizes cut-through forwarding to minimize latency for high-performance control applications.

Specialized Applications

• Industrial Ethernet infrastructure requiring time synchronization
• Embedded solutions utilizing Device Level Ring redundancy
• High-performance control networks such as CIP Motion

Specialized Procurement Notes

Verify the specific package type required for the design, as the datasheet lists both LQFP and BGA options. Confirm that the host CPU interface supports the necessary MII signals and flow control mechanisms. Ensure the operating environment falls within the specified industrial temperature range. Check for any software dependencies related to DLR or IEEE 1588 configuration.

Specialized Selection Notes

Select this component when a managed Layer 2 switch with integrated time synchronization is needed. It is suitable for designs requiring DLR redundancy without complex external controllers. Consider the available package options based on board space constraints. Verify compatibility with the host processor's MAC capabilities before finalizing the selection.

Specialized FAQ

What network topologies does the FIDO2100 support?

The device supports hierarchical star, daisy chain, hybrid daisy chain hierarchical star, and DLR media redundancy topologies.

How does the device handle broadcast storms?

It implements a prevention mechanism that drops additional broadcast frames if received data exceeds approximately 1% of network bandwidth within a 100 millisecond period at 100Mbps speed.

What is the function of the internal port?

The internal port connects to the host CPU, allowing the device to act as a managed switch while offloading traffic processing from the main processor.
