SY100EP58VKG

Signal Switches, Multiplexers, Decoders Overview

The SY100EP58VKG is a high-speed 2:1 multiplexer from the ECL Pro family, manufactured by Microchip Technology. It operates on a flexible supply voltage ranging from +3.0V to +5.5V and supports an industrial temperature range of –40°C to +85°C. The device guarantees a maximum toggle frequency (fMAX) exceeding 3GHz with a differential output swing of at least 400mV. Propagation delay from data input to output is specified between 170ps and 420ps depending on operating conditions. The component utilizes an 8-lead MSOP package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead finish. Confirm whether the procurement requires tape and reel packaging or tube quantities. Ensure the revision level aligns with current design specifications. Check for any recent product change notifications regarding manufacturing sites or material composition updates before finalizing orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring high-speed data routing with minimal signal degradation. The internal temperature compensation ensures stable logic levels without external adjustments. Verify that the system power supply falls within the 3.0V to 5.5V range. Ensure proper termination networks are implemented to maintain signal integrity at frequencies approaching 3GHz.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SY10/100EP58V series, which serves as a pin-for-pin replacement for legacy MC10/100EP58D devices. The '100' designation indicates 100KEP technology, providing enhanced performance characteristics compared to standard ECL families. The device is part of Micrel's Precision Edge timing and distribution portfolio, now managed under Microchip Technology.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SY100EP58VKG is a direct pin-compatible substitute for the MC100EP58DT in 8-pin MSOP packages. Designers transitioning from older Micrel parts should verify that existing PCB layouts support the updated electrical characteristics and termination requirements specified in the current datasheet.

Signal Switches, Multiplexers, Decoders FAQ

How does the SY100EP58VKG handle floating inputs?

The signal-path inputs include internal 75kΩ pull-down resistors, establishing a default LOW condition if left unconnected. However, external termination is recommended for optimal AC performance.

What is the common mode input voltage range?

For 100KEP technology, the input high common mode range is specified from VEE + 2.0V up to 0.0V relative to VEE, ensuring compatibility with various ECL and PECL signaling standards.
