SY100EP56VK4C

Signal Switches, Multiplexers, Decoders Overview

The SY100EP56VK4C is a dual differential 2:1 multiplexer from the ECL Pro family, designed for high-speed PECL/ECL applications. It operates within a supply voltage range of 3.0V to 5.5V and supports toggle frequencies exceeding 3GHz. The device features two independent channels with dedicated select control pins (SEL0, SEL1) or a common select pin (COM_SEL). Propagation delay is guaranteed at a maximum of 500ps across all signal paths. Internal 75k pull-down resistors are provided on inputs and selects. It is housed in a 20-pin TSSOP package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering code suffix against the manufacturer's current product line. Confirm that the commercial operating temperature range (-40°C to +85°C) aligns with system requirements. Ensure proper termination schemes are implemented for PECL/ECL logic levels to maintain signal integrity. Check for any recent process change notifications regarding the K4-20-1 package type.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual-channel differential multiplexing is required with low skew characteristics. The device accommodates both independent and common select control configurations. Consider the internal pull-down resistors for default state management. Evaluate the 500ps propagation delay limit against system timing budgets. Verify compatibility with existing PECL or ECL driver and receiver circuits.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Micrel ECL Pro family of high-speed timing and distribution devices. It serves as a pin-for-pin replacement for the MC10/100EP56DT series. The device integrates advanced emitter-coupled logic technology optimized for minimal jitter and precise edge timing. It complements other components like fanout buffers and translators within the same product portfolio.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The datasheet identifies the MC100EP56DT and MC100EP56DTR2 as direct cross-reference replacements. These parts share identical functionality and pinout configurations. Verify that substitute sources confirm the same electrical specifications and package dimensions.
