SY55855VKI

Translators, Level Shifters Overview

The SY55855VKI is a dual CML/PECL/LVPECL-to-LVDS translator from the SuperLite family. It supports throughput up to 1.5Gbps with guaranteed maximum operating frequency exceeding 750MHz across the temperature range. Propagation delay is less than 700ps, and within-device skew is under 50ps. The device operates on a 3.0V to 5.7V supply and features fully differential I/O architecture with LVDS compatible outputs. It is housed in a 10-pin MSOP package.

Translators, Level Shifters Feature Summary

• Translates CML, PECL, or LVPECL signals to LVDS format
• Fully differential input and output architecture for high signal integrity
• Capable of driving 50-ohm impedance transmission line media

Translators, Level Shifters Applications

• High-speed logic systems
• Data communications systems
• Wireless communications systems

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm lead finish and packaging type. The 'KI' suffix indicates an industrial temperature range variant with Sn-Pb lead finish. Confirm RoHS compliance requirements if Pb-free versions are necessary for the design.

Translators, Level Shifters Selection Notes

Select this component when interfacing legacy CML, PECL, or LVPECL sources with modern LVDS receivers. Ensure the system power supply falls within the 3.0V to 5.7V operational range. Verify that the required data rate does not exceed the 1.5Gbps capability and that the 10-pin MSOP package fits the board layout constraints.

Translators, Level Shifters Part Context

This part belongs to Micrel’s SuperLite family of high-speed logic devices, characterized by small packaging and operation at various supply voltages. Micrel was acquired by Microchip Technology, which now manages the product line. The device serves as a bridge between different high-speed signaling standards in complex electronic architectures.

Translators, Level Shifters Replacement Considerations

Check the official datasheet for equivalent Pb-free options such as the SY55855VKG series. Verify pin compatibility and electrical specifications before substituting.
