MAX22088GTG+T

Overview

The MAX22088GTG+T is a Home Bus System (HBS) compatible transceiver manufactured by Analog Devices Inc./Maxim Integrated. Designed for applications requiring data and power transmission over a single pair of wires, this device minimizes external component requirements through integrated dynamic cable termination. It supports data rates up to 200 kbps on 1000-meter UTP cables. The transceiver features a configurable architecture with adjustable slew rates for low EMI and programmable receiver thresholds. It operates within a temperature range of -40°C to +125°C and is housed in a compact 4 mm x 4 mm TQFN package.

Feature Summary

• Dynamic cable termination enhances signal quality for high-speed communication over extended cable lengths.
• Integrated protection mechanisms ensure robustness against electrostatic discharge and electrical surges.
• Configurable communication parameters allow optimization for specific system requirements and electromagnetic compatibility.

Applications

• Heating, Ventilation, and Air Conditioning (HVAC) systems
• Building automation controllers
• Industrial Internet of Things (IIoT) networks
• Simplified Home Bus System (HBS) implementations

Procurement Notes

Verify the specific suffix GTG+T against official datasheets to confirm package type and tape-and-reel configuration. Ensure compliance with RoHS directives as indicated by the plus sign. Cross-reference availability with authorized distributors, as stock levels fluctuate. Confirm that the operating voltage and temperature ranges align with the target application environment before procurement.

Selection Notes

Select the MAX22088GTG+T when designing HBS-compliant networks requiring long-distance communication over twisted pair wiring. Consider its pin-to-pin compatibility with the MAX22088 if upgrading existing designs. Evaluate the need for dynamic termination to mitigate signal reflections in longer cable runs. Assess EMI constraints to determine if the adjustable slew rate feature is necessary for the specific installation environment.

Part Context

This component belongs to the MAX2208x series of Home Bus System transceivers. It serves as a physical layer interface for standardized building automation protocols. The device addresses the need for reliable, low-cost communication in environments where traditional Ethernet or USB solutions are impractical due to cabling complexity or distance limitations.

Replacement Considerations

The MAX22088 is explicitly noted as pin-to-pin compatible with the MAX22088. Verify functional equivalence and package dimensions before substitution. No other direct substitutes are documented in the provided reference material.
