MC10E445FNR2G

Overview

The MC10E445FNR2G is a 4-bit serial-to-parallel data converter manufactured by onsemi. It operates at NRZ data rates up to 2.0 Gb/s and supports both PECL (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL (VCC = 0 V, VEE = -4.2 V to -5.7 V) logic families. The device features dual selectable differential serial inputs, asynchronous synchronization via the SYNC pin, and internal divide-by-4 and divide-by-8 clock outputs. It is housed in a PLCC-28 package with an operating temperature range of 0°C to +85°C.

Feature Summary

• Dual selectable differential serial inputs enable loopback testing when paired with the E446 parallel-to-serial converter.
• Asynchronous data synchronization allows shifting the conversion start bit using the SYNC input pulse.
• Integrated divide-by-4 and divide-by-8 clock outputs facilitate system synchronization and cascaded 8-bit conversion schemes.

Applications

• High-speed serial-to-parallel data conversion for telecommunications systems
• Loopback testing architectures utilizing the E446 converter
• Cascaded 1:8 demultiplexer configurations

Procurement Notes

Verify that the ordering suffix 'G' confirms Pb-Free status as specified in the datasheet. Confirm the package type is PLCC-28 and check the moisture sensitivity level requirements during storage and handling. Ensure power supply connections match the selected PECL or NECL mode specifications.

Selection Notes

Select this component for applications requiring up to 2.0 Gb/s NRZ data rate processing. Choose between the standard MC10E445 or temperature-compensated MC100E445 variants based on environmental needs. Ensure the design accommodates the specific voltage ranges for PECL or NECL operation modes.

Part Context

This part belongs to the MC10/100E445 series of integrated 4-bit serial-to-parallel converters. It is designed to work in conjunction with the E446 parallel-to-serial converter to establish high-speed serial data paths. The series includes both standard and temperature-compensated versions within the same functional family.

Replacement Considerations

MC100E445FNR2G offers temperature compensation compared to the standard MC10E445FNR2G. Both share identical pinouts and electrical characteristics except for thermal performance variations across the operating temperature range.

FAQ

How does the SYNC input function?

The SYNC input allows asynchronous shifting of the conversion start bit. A single pulse shifts the start bit from Qn to Qn-1, and additional pulses shift it further.

What is the purpose of the MODE input?

The MODE input selects between 4-bit conversion (LOW or open) and 8-bit conversion (HIGH). In 8-bit mode, two devices are cascaded to process 8 bits of data.

Can the device support loopback testing?

Yes, the device has two selectable serial inputs (SINA and SINB) that provide loopback capability when used with the E446 parallel-to-serial converter.
