SY100EP56VK4G-TR

Signal Switches, Multiplexers, Decoders Overview

The SY100EP56VK4G-TR is a dual fully differential 2:1 multiplexer from the ECL Pro family, designed for high-speed signal routing. It supports PECL, LVPECL, ECL, and LVECL logic standards with a flexible power supply range of 3.0V to 5.5V. The device guarantees AC performance over an industrial temperature range of –40°C to +85°C. Key electrical specifications include a maximum toggle frequency exceeding 3GHz, propagation delay up to 500ps, and within-device skew under 100ps. It is housed in a 20-pin TSSOP package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual independent channels with dedicated or common select control
• Fully differential inputs accepting signals as low as 150mV pk-pk
• Integrated VBB reference outputs for AC-coupled applications
• Internal pull-down resistors on all I/O pins

Signal Switches, Multiplexers, Decoders Applications

• High-speed clock distribution networks
• Signal routing in telecommunications infrastructure
• Data acquisition systems requiring low-skew switching
• Test and measurement equipment interfaces

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the component matches the specific Micrel/SY100EP56VK4G-TR designation rather than generic equivalents. Confirm the presence of the Pb-Free bar-line indicator and NiPdAu lead finish. Ensure the supplier provides documentation confirming the 20-pin TSSOP package type and compliance with RoHS directives for new design implementations.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual-channel differential multiplexing is required at frequencies above 3GHz. It serves as a pin-for-pin replacement for the MC10/100EP56DT series. Consider its compatibility with both positive and negative supply configurations. Evaluate the internal 75kΩ pull-down resistors for simplified biasing requirements in single-ended or AC-coupled designs.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the ECL Pro family of high-speed timing and distribution devices originally developed by Micrel, now Microchip Technology. The 'K4' suffix indicates the 20-pin TSSOP package, while 'G' denotes Pb-free construction. The '-TR' suffix specifies tape and reel packaging. This family focuses on precision edge timing solutions for demanding digital applications.
