MAX2986CXE+D

Telecom Overview

The MAX2986CXE+D is a single-chip integrated powerline digital transceiver combining MAC and PHY layers. It supports data rates up to 14Mbps using OFDM with 84 carriers in the 4.49MHz to 20.7MHz band. The device features 128kB internal SRAM, JTAG interface, and a bridge table for up to 512 addresses. Power supply requirements include VDD33 at 3.0V to 3.6V and core supplies (VDD18, DVDD, AVDD) at 1.62V to 1.98V. Digital I/O supply current is typically 41mA, while core supply current is 426mA. It operates within a temperature range of 0°C to +70°C.

• Home Automation
• Industrial Automation Remote Monitoring and Control

Telecom Procurement Notes

Verify the specific suffix 'CXE+D' against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the companion MAX2980 analog front-end for complete system operation. Confirm RoHS compliance status and lead-free soldering requirements during procurement.

Telecom Selection Notes

Select this component for applications requiring high-speed powerline communication with HomePlug 1.0 interoperability. Consider the 144-pin CSBGA package constraints for PCB layout. Evaluate the need for external memory or if the onboard 128kB SRAM suffices. Verify interface requirements for MII, rMII, FIFO, or USB connectivity before finalizing the design.

Telecom Part Context

The MAX2986 series represents a highly integrated solution for powerline networking, merging digital baseband processing with physical layer modulation. It is designed to work alongside the MAX2980 AFE to provide a complete chipset solution. This integration reduces system cost and complexity compared to discrete MAC and PHY implementations.
