LX128EV-5F208I

Overview

The LX128EV-5F208I is a digital crosspoint switch from the Lattice E-Series, designed for high-speed signal routing. It features a 128 x 128 I/O matrix configuration and supports data rates up to 21 Gb/s. The device operates on a 2.5 V supply voltage with a specified propagation delay of 5 ns. It accommodates multiple input and output types, including Bus LVDS, LVCMOS, LVPECL, and LVTTL. Packaged in an FPBGA-208 format, it functions within a commercial temperature range of 0°C to +90°C.

Feature Summary

• Provides flexible signal routing through a 128 x 128 crosspoint matrix architecture
• Supports mixed-signal interfaces including LVDS, LVCMOS, LVPECL, and LVTTL standards
• Enables high-speed data transmission with low latency switching capabilities

Applications

• High-speed serial backplane interconnects
• Signal distribution in telecommunications infrastructure
• Test and measurement equipment signal routing

Procurement Notes

Verify component authenticity as this specific part number may be subject to end-of-life status or limited availability. Confirm that the industrial temperature grade suffix matches system requirements. Ensure compatibility with existing power delivery networks operating at 2.5V. Validate package footprint against current PCB design files before procurement.

Selection Notes

Select this component when a dense 128x128 switching matrix is required for mixed-signal environments. Compare against other E-Series variants based on specific voltage levels and speed grades. Ensure the FPBGA-208 package fits the thermal and spatial constraints of the target application board.

Part Context

This device belongs to the Lattice E-Series family of analog and digital crosspoint ICs. These components are engineered for communication and networking applications requiring reliable signal path management. The series offers scalable solutions for complex interconnect topologies in demanding electronic systems.

Replacement Considerations

Check for direct substitutes within the LX128EB or LX128EV families. Verify if lower speed grades like LX128EV-32F208C meet timing requirements. Consider newer generation crosspoint switches if EOL status prevents long-term sourcing.
