VMC10E111FN

Overview

The MC10E111FN is a low skew 1-to-9 differential clock driver manufactured by onsemi. It accepts one signal input, which can be differential or single-ended using the VBB output, and fans it out to nine identical differential outputs. The device includes an enable input that disables the device by forcing Q outputs LOW and Q_bar outputs HIGH when active. Designed for clock distribution, it features guaranteed skew specifications, internal input 50 kΩ pulldown resistors, and ESD protection exceeding 3 kV via the Human Body Model. It operates in PECL mode with VCC from 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VEE from -4.2 V to -5.7 V (VCC = 0 V).

Applications

• Clock Distribution Systems
• High-Speed Digital Signal Processing
• Telecommunications Equipment

Procurement Notes

Verify component authenticity as the MC10E111FN is listed as obsolete. Check for moisture sensitivity level compliance, specifically MSL 3 for lead-free packages. Confirm package integrity for the 28-PLCC form factor before integration into production lines.

Selection Notes

Select this component for applications requiring a single differential input to fan out to nine differential outputs with low skew. Ensure supply voltage aligns with PECL (4.2V–5.7V) or NECL (-4.2V to -5.7V) requirements. Consider the 28-PLCC package constraints and surface mount installation type during PCB layout.

Part Context

The MC10E111FN belongs to the MC10E/100E series of high-speed logic devices. It is functionally similar to other 1:9 differential drivers in the ECL family but is distinguished by its specific operating voltage ranges and pinout configuration in the 28-PLCC package. It serves as a critical component for maintaining signal integrity in high-frequency clock networks.

Replacement Considerations

Direct replacements may be limited due to the obsolete status. Evaluate functional equivalents within the MC10E series or newer generations from onsemi that offer compatible 1:9 differential fanout capabilities and similar pinouts.
