SY100EPT21LZG-TR

Translators, Level Shifters Overview

The SY100EPT21LZG-TR is a single differential LVPECL-to-LVTTL translator from the ECL Pro family, manufactured by Microchip Technology. It operates on a single +3.3V power supply and features a typical propagation delay of 1.9ns with a maximum frequency of 275MHz. The device accepts differential LVPECL inputs and provides a 24mA LVTTL output in an 8-pin SOIC package. It is guaranteed for operation across the industrial temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Supports differential LVPECL input signals converted to standard LVTTL logic levels
• Includes a VBB reference voltage output for flexible interface configurations
• Provides added stability by forcing the Q output low under open input conditions

Translators, Level Shifters Applications

• ASIC/FPGA interface connections
• Legacy system interface translation
• Precision differential-to-general purpose single-ended signal translation

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required industrial temperature range (-40°C to +85°C) and the lead finish specifications. Confirm the package type corresponds to the design footprint requirements. Ensure compliance with RoHS directives if applicable to the manufacturing batch. Cross-reference the part number against official manufacturer documentation to confirm current production status and availability.

Translators, Level Shifters Selection Notes

Select this component when minimal space, low power consumption, and cost efficiency are critical for clock or data signal translation. It serves as a pin-for-pin replacement for MC100EPT21D/DT devices. Consider alternative packages like MSOP for smaller footprints if board real estate is extremely limited.

Translators, Level Shifters Part Context

This device belongs to the ECL Pro family of high-speed logic components designed for precision timing applications. It bridges the gap between low-voltage positive ECL standards and general-purpose TTL logic families. The technology supports high-frequency operations suitable for modern digital communication systems requiring reliable level shifting.

Translators, Level Shifters FAQ

How does the device behave when the differential inputs are left open?

Under open input conditions, the /D input is biased at a VCC/2 voltage level while the D input is pulled to ground. This configuration forces the Q output low to provide added circuit stability.

What is the function of the VBB pin?

The VBB pin serves as an output reference voltage that allows for differential, single-ended, or AC-coupled interfaces to the device. If utilized, it should be bypassed to VCC with a 0.01 µF capacitor.
