MC10E446FNR2G

Overview

The MC10E446FNR2G is a 5V EnECL integrated 4-bit parallel to serial data converter manufactured by onsemi. It operates within a supply voltage range of 4.2 V to 5.7 V and supports NRZ data rates up to 1.3 Gb/s, with typical capability reaching 1.5 Gb/s. The device converts four parallel data inputs (D0-D3) into a single serial output stream (SOUT). It includes internal divide-by-4 and divide-by-8 clock outputs for synchronization and features an asynchronous SYNC input to reset the conversion sequence. The component is housed in a 28-pin PLCC package.

Feature Summary

• Integrated divide-by-4 and divide-by-8 clock generation circuitry
• Asynchronous data synchronization via dedicated SYNC pin
• Mode select functionality to expand conversion capacity to 8 bits using two cascaded devices
• Internal reference voltage output (VBB) for single-ended input applications

Applications

• High-speed parallel to serial data conversion
• Cascaded 8-bit multiplexer architectures
• Data management interface systems

Procurement Notes

Verify that the specific ordering suffix FNR2G corresponds to the Tape & Reel packaging format and lead-free status as documented in official manufacturer catalogs. Confirm the part status remains current or obsolete depending on the required production timeline. Ensure compatibility with the specified PECL or NECL operating ranges during the procurement phase.

Selection Notes

Select this component when a high-speed 4:1 parallel-to-serial conversion function is required within the EnECL logic family. Verify that the system design accommodates the differential clock and serial input requirements. Consider the thermal resistance characteristics if operating at maximum data rates, and ensure proper termination networks are implemented for ECL signal integrity.

Part Context

This component belongs to the MC10E/100E446 series of 5V EnECL converters. The '10' prefix indicates standard operation, while the '100' variant offers temperature compensation. The base product number is MC10E446. This specific part integrates the converter logic with a 28-PLCC surface mount package designed for automated assembly processes.
