MAX24188ETK2T

Overview

The MAX24188ETK2T is a clock synthesizer integrated circuit designed for Ethernet applications. It operates within a supply voltage range of 1.14V to 3.465V and supports a maximum frequency of 125MHz. The device features one circuit with a 1:2 input-to-output ratio and lacks differential inputs or outputs. It is housed in a 68-WFQFN package with an exposed pad, suitable for surface mount installation. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated PLL-based clock synthesizer optimized for Ethernet timing
• Supports 1:2 input-to-output frequency ratio with single circuit configuration
• Operates on a wide supply voltage range from 1.14V to 3.465V
• Housed in a compact 68-TQFN-EP (8x8) surface-mount package

Applications

• Ethernet network interface synchronization
• Clock distribution in Ethernet switch systems
• Frequency synthesis for 1Gbps/10Gbps Ethernet PHY interfaces

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape-and-reel packaging quantities and lead times. Ensure the 68-TQFN-EP footprint matches the PCB design requirements. Confirm RoHS compliance status through official datasheets before procurement.

Selection Notes

Select this component when a dedicated Ethernet clock synthesizer with a 1:2 ratio is required. Verify that the 125MHz maximum frequency meets system timing constraints. Ensure the 1.14V to 3.465V supply range aligns with the target board power rails. Check thermal performance within the -40°C to +85°C industrial range.

Part Context

This part belongs to the MAX24188 family of Ethernet clock generators. It serves as a specialized interface solution for synchronizing clocks in high-speed Ethernet networks. The device integrates phase-locked loop functionality to generate precise output frequencies from a single reference input.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify electrical parameters such as supply voltage and maximum frequency match the original design requirements.
