MAX9181EXT-T

Translators, Level Shifters Overview

The MAX9181EXT-T is a low-jitter, low-noise LVPECL-to-LVDS level translator manufactured by Analog Devices Inc./Maxim Integrated. It accepts a single differential LVPECL input and translates it to a single LVDS output. The device operates from a single 3.3V supply (3.0V to 3.6V range) with a typical supply current of 10mA. It guarantees a data rate of 400Mbps and features ultra-low added jitter of 23ps P-P deterministic and 0.6ps RMS random. The component is housed in a compact 6-pin SC70 package and functions within an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides high-impedance inputs and outputs during power-down mode

Translators, Level Shifters Applications

• Digital Cross-Connects
• Add/Drop Muxes
• Network Switches/Routers
• Cellular Phone Base Stations
• DSLAMs

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix EXT-T corresponds to the -40°C to +85°C temperature range and SC70-6 package configuration. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer's documentation. Ensure compatibility with 3.3V logic levels and proper termination resistances for LVDS interfaces before integration into the design.

Translators, Level Shifters Selection Notes

Select this component when interfacing between LVPECL drivers and LVDS receivers requiring minimal signal degradation. It is suitable for applications sensitive to timing errors, such as those incorporating clock-and-data recovery circuits or PLLs. Consider the small SC70 footprint for space-constrained designs and verify that the 400Mbps data rate meets system bandwidth requirements.

Translators, Level Shifters Part Context

This part belongs to the MAX9181 series of interface translators designed for high-speed digital systems. It complements other Maxim Integrated interface solutions like the MAX9180 LVDS repeater. The device addresses the need for efficient protocol conversion between different signaling standards while maintaining signal integrity in dense electronic environments.

Translators, Level Shifters Replacement Considerations

Refer to the MAX9180 datasheet for a comparable low-jitter, low-noise LVDS repeater solution in an SC70 package. Verify pinout and electrical specifications against alternative translators if direct substitution is required.
