MC100EP57MNTXG

Overview

The MC100EP57MNTXG is a fully differential 4:1 multiplexer from the onsemi MC100EP series, designed for high-speed digital applications. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE ranging from -3.0 V to -5.5 V (VCC = 0 V). The device features typical propagation delays of 375 ps and supports maximum frequencies exceeding 2 GHz. It includes internal input pulldown resistors, safety clamps, and multiple VBB outputs for reference voltage generation. The component is housed in a QFN-20 package.

Feature Summary

• Fully differential architecture suitable for low skew applications such as clock distribution
• Configurable as either a 4:1 or 2:1 multiplexer by leaving the SEL1 line open
• Includes temperature compensation within the 100 Series for stable performance across operating temperatures
• Provides multiple VBB outputs that can be used as switching reference voltages or to rebias AC coupled inputs

Applications

• Clock distribution systems requiring low skew
• High-speed data routing and signal selection
• Differential logic circuits operating in PECL or NECL modes

Procurement Notes

Verify the specific suffix 'MNTXG' corresponds to the QFN-20 Tape & Reel packaging variant. Confirm current status as discontinued for new designs per official documentation. Ensure compatibility with existing PCB footprints and thermal requirements associated with the exposed pad connection to VEE.

Selection Notes

Select this component when a fully differential ECL multiplexer with temperature compensation is required. Consider the QFN-20 package constraints and the need for external power supply connections to all VCC and VEE pins. Evaluate if the 375 ps propagation delay meets system timing requirements compared to other available logic families.

Part Context

This part belongs to the MC10/100EP family of high-speed ECL devices. The '100' designation indicates the inclusion of temperature compensation features not present in the standard '10' series. It serves as a specialized logic IC for maintaining signal integrity in high-frequency differential environments.

Replacement Considerations

MC10EP57MNG is listed as a parameter equivalent alternative.
