MC100EP56MNG

Overview

The MC100EP56MNG is a dual, fully differential 2:1 multiplexer from the onsemi MC100EP series, designed for low skew clock or skew-sensitive signal multiplexing. 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 360 ps and supports maximum frequencies exceeding 3 GHz. It includes separate and common select inputs, internal temperature compensation, and multiple VBB pins for switching reference voltage generation. The component is housed in a QFN-20 package.

Feature Summary

• Dual fully differential data path optimized for low skew applications
• Internal temperature compensation within the 100 Series architecture
• Multiple VBB pins providing internally generated reference voltage
• Separate and common select inputs for flexible logic control

Applications

• Multiplexing low skew clock signals
• Skew-sensitive signal routing
• Random logic applications requiring differential inputs

Procurement Notes

Verify that the MC100EP56MNG is marked as discontinued by onsemi and not recommended for new designs. Confirm availability through authorized distributors for existing production runs. Ensure compliance with RoHS standards and lead-free packaging requirements during procurement. Check specific ordering suffixes for tube quantities and verify assembly location codes if traceability is required.

Selection Notes

Select this component when differential signal integrity and minimal skew are critical. The MC100EP56MNG suits designs requiring high-speed operation above 3 GHz with ECL-compatible logic levels. Consider the QFN-20 package constraints and thermal dissipation needs. Verify power supply configurations for either PECL or NECL modes before integration into the system architecture.

Part Context

This part belongs to the MC10/100EP56 family of dual differential 2:1 multiplexers. The 100 Series specifically incorporates temperature compensation compared to the standard 10 Series. It is manufactured by onsemi and utilizes ECL technology for high-frequency performance. The device is available in various packages including SOIC-20, TSSOP-20, and QFN-20.

Replacement Considerations

The datasheet lists MC10EP56MNG as an alternative within the same family but also marks it as discontinued. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
