SY55857LKI

Translators, Level Shifters Overview

The SY55857LKI is a dual translator IC from the SuperLite series, designed to convert various logic standards into LVPECL. It accepts single-ended inputs (SSTL, TTL, CMOS) and differential signals (LVDS, HSTL, CML). The device supports data rates up to 2.5Gbps with propagation delays under 400ps. Operating on a 3.0V to 3.6V supply, it consumes approximately 46mW per channel. Packaged in a 10-pin MSOP.

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized Microchip Technology channels. Confirm RoHS compliance status as the specific K suffix indicates Sn-Pb finish which may not meet current environmental regulations. Check lead availability and substitute options like the Pb-Free LKG variant if required by manufacturing specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing mixed logic families to LVPECL outputs is required. Ensure input voltage swings match the supported ranges for desired speed. Verify thermal management capabilities within the MSOP package. Consider the Pb-Free alternative if environmental compliance is mandatory for the target application.

Translators, Level Shifters Part Context

Part of the SuperLite family optimized for high-speed signal translation. Manufactured originally by Micrel, now part of Microchip Technology. Designed for applications requiring robust conversion between disparate logic standards while maintaining signal integrity at gigabit speeds.

Translators, Level Shifters Replacement Considerations

SY55857LKG is a direct replacement offering Pb-free construction with NiPdAu lead finish. Both share identical electrical characteristics and pinouts. Verify packaging preferences and environmental compliance requirements before substitution.

Translators, Level Shifters FAQ

Does the SY55857L internally terminate its inputs?

No, the device does not internally terminate its inputs to accommodate different interfacing standards with varying termination requirements.
