MC100E446FNG

Specialized Overview

The MC100E446FNG is a 5V/EnECL 4-bit parallel to serial converter manufactured by onsemi. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V and VEE at 0 V, or NECL mode with VCC at 0 V and VEE from -4.2 V to -5.7 V. The device converts four bits of parallel data into a serial stream at NRZ data rates up to 1.3 Gb/s. It includes internal divide-by-4 and divide-by-8 clock outputs, asynchronous synchronization via the SYNC input, and a MODE pin for cascading two devices for 8-bit conversion. The component is housed in a 28-pin PLCC package.

Specialized Feature Summary

• Integrated 4-bit parallel to serial data conversion capability
• On-chip divide-by-4 and divide-by-8 clock generation
• Asynchronous data synchronization and mode selection for expansion

Specialized Applications

• High-speed serial data path transmission systems
• Cascaded 8:1 multiplexer architectures using dual E446 devices
• NRZ data rate conversion for telecommunications interfaces

Specialized Procurement Notes

Verify the specific ordering suffix 'FN' indicates a standard tube packaging configuration rather than tape and reel. Confirm that the 'G' suffix denotes lead-free compliance as per manufacturer standards. Ensure the procurement matches the exact MC100E446FNG designation to guarantee correct package type and environmental specifications.

Specialized Selection Notes

Select this component when a 4-bit parallel to serial conversion function is required within an EnECL logic family. Consider the MC100E446FNG over the MC10E446 variant if temperature compensation features are necessary for the application environment. Verify power supply requirements align with either PECL or NECL operating ranges before integration.

Specialized Part Context

This part belongs to the MC10E/100E446 series of integrated circuits designed for high-speed data conversion. The 100 Series specifically incorporates temperature compensation compared to the base 10 Series. It is intended for use with companion devices like the E445 to establish complete high-speed serial data transmission paths.

Specialized Replacement Considerations

The MC10E446FNG serves as a functional equivalent to the MC100E446FNG, differing primarily in temperature compensation characteristics. Direct substitution requires verifying that the application can tolerate the performance variations between the 10 and 100 series under specific thermal conditions.
