SY100E457JZ

Signal Switches, Multiplexers, Decoders Overview

The SY100E457JZ is a triple differential 2:1 multiplexer manufactured by Microchip Technology, housed in a 28-pin PLCC package. It operates within an extended VEE range of –4.2V to –5.5V and features a maximum propagation delay of 700ps. The device provides high-frequency outputs with a bandwidth exceeding 1.0GHz, making it suitable for demanding system clock applications. It includes separate and common select inputs, internal 75KΩ input pulldown resistors, and a VBB output for single-ended use.

Signal Switches, Multiplexers, Decoders Feature Summary

• Fully differential data path designed for low skew clock or skew-sensitive signal multiplexing
• High-frequency outputs providing greater than 1.0GHz bandwidth
• Supports both separate and common select configurations for data path and random logic applications

Signal Switches, Multiplexers, Decoders Applications

• Multiplexing low skew clock signals
• Multiplexing other skew sensitive signals
• Data path applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm that the JZ suffix indicates a lead-free package with a matte tin finish and a Pb-Free bar-line indicator. Ensure compatibility with the commercial operating temperature range and the specific 28-pin PLCC form factor required for your PCB layout.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a triple differential 2:1 multiplexer with high-speed performance is required. It is appropriate for systems needing an extended negative supply voltage range down to -4.2V. Consider the availability of separate versus common select inputs based on control logic requirements and verify the need for internal pulldown resistors.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SY10/100E457 series of triple differential 2:1 multiplexers originally developed by Micrel, Inc., now under Microchip Technology. The series is characterized by its ECL-compatible operation and fully differential architecture, intended for high-performance digital systems requiring precise timing and signal integrity.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the VBB pin?

The VBB pin serves as a reference output that can be used for single-ended applications.

Does the device support individual channel selection?

Yes, the device provides individual select inputs (SEL) for each of the three multiplexers, in addition to a common select input (COMSEL).
