SY100E445JZ-TR

Specialized Overview

The SY100E445JZ-TR is a 4-bit serial-to-parallel data converter manufactured by Microchip Technology, operating within the ECL logic family. It supports NRZ data rates up to 2.5 Gb/s and functions with a supply voltage range of -4.2V to -5.5V. The device features dual differential serial inputs (SINA/SINB), a selectable input pin (SEL), and provides four parallel outputs (Q0-Q3). Internal clock dividers generate ÷4 and ÷8 differential clock outputs. It is housed in a 28-pin PLCC package.

Specialized Feature Summary

• Dual differential serial inputs enable loopback testing when paired with compatible parallel-to-serial converters.
• Integrated asynchronous synchronization allows shifting the conversion start bit via the SYNC input.
• Mode select capability expands functionality from 4-bit to 8-bit conversion using two cascaded devices.

Specialized Applications

• High-speed serial-to-parallel demultiplexing for data streams up to 2.5Gb/s
• Loopback testing architectures utilizing paired serial-to-parallel and parallel-to-serial converters
• Cascaded configurations forming 1:8 demultiplexers for extended parallel data paths

Specialized Procurement Notes

Verify component authenticity through authorized channels as this part originates from Micrel, now part of Microchip. Confirm RoHS compliance status and lead finish specifications corresponding to the JZ suffix. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific ordering code matches the required tape and reel packaging format.

Specialized Selection Notes

Select this component for applications requiring high-speed ECL serial data reception. Ensure system design accommodates the negative setup time characteristics of the serial inputs. Verify that power supply rails strictly adhere to the specified -4.2V to -5.5V range. Consider thermal management requirements associated with the typical 154mA power consumption at standard operating conditions.

Specialized Part Context

This device belongs to the SY10/100E series of high-speed ECL logic components originally developed by Micrel. The '100' prefix indicates operation within the extended VEE range suitable for lower noise environments compared to standard ECL. The JZ suffix denotes a Pb-free package variant with a matte tin lead finish, recommended for new designs to meet environmental compliance standards.

Specialized Replacement Considerations

The SY10E445JC is functionally equivalent but utilizes Sn-Pb lead finish. Standard MC10E445 or MC100E445 parts from Motorola are fully compatible replacements. Verify that any substitute maintains the same 28-pin PLCC footprint and electrical characteristics for direct board replacement.
