GSW140A3LC

Controllers Overview

The MaxLinear GSW140A3LC is a highly integrated, low-power, non-blocking six-port Gigabit Ethernet switch featuring four Ethernet PHYs, one 1G/2.5G SGMII+ interface, and one management port. It supports IEEE 802.3 standards including 10BASE-T, 100BASE-TX, and 1000BASE-T. The device operates at a supply voltage of 1.05V to 1.15V within an industrial temperature range of 0°C to +70°C. It utilizes an LLGA-105 (8x8) package and provides interfaces such as RGMII, SGMII, SPI, and UART for system connectivity.

Controllers Feature Summary

• Integrates four Ethernet PHY transceivers with a dedicated management port for comprehensive network connectivity
• Supports high-speed data rates up to 2.5 Gb/s via the SGMII+ interface alongside standard Gigabit speeds
• Provides flexible digital I/O and serial communication interfaces including SPI and UART for configuration

Controllers Applications

• Industrial networking equipment requiring robust Gigabit connectivity
• Consumer electronic devices needing integrated Ethernet switching capabilities
• Digital systems utilizing SGMII+ backplane connections

Controllers Procurement Notes

Verify the specific suffix 'LC' against official MaxLinear documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and voltage levels. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential end-of-life notices prior to finalizing procurement plans.

Controllers Selection Notes

Select this component when a compact, low-power solution is required for multi-port Ethernet applications. The LLGA-105 package suits space-constrained designs. Verify that the host processor supports the necessary RGMII or SGMII interfaces. Confirm that the 1.1V core voltage aligns with the system power architecture before integration into the design.

Controllers Part Context

This part belongs to the GSW140 family of highly integrated Ethernet switches from MaxLinear. The series is designed for applications demanding low latency and high throughput in a small form factor. The GSW140A3LC variant specifically denotes the LLGA package option, distinguishing it from other pinout or thermal variants within the same functional family.

Controllers Replacement Considerations

Consult official MaxLinear substitution guides for verified alternatives. The GSW140A3MC is a related variant using an MRQFN package; verify pin compatibility and thermal requirements before considering cross-package replacements.
