SY100EPT21LKG

Translators, Level Shifters Overview

The SY100EPT21LKG is a single differential LVPECL-to-LVTTL translator 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 input frequency of 275MHz. The device provides a 24mA LVTTL output and includes a VBB reference voltage output. It is housed in an 8-pin MSOP package and is guaranteed to operate within the industrial temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V power supply
• Includes a VBB output for configuring differential, single-ended, or AC-coupled interfaces
• Ensures stability under open input conditions by forcing the Q output low
• Compatible with positive ECL 100K logic levels

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify that the component corresponds to the specific Industrial grade variant with Pb-Free NiPdAu lead finish. Confirm the package type matches the required 8-pin MSOP footprint. Ensure the design accounts for the single +3.3V power supply requirement and proper bypassing of the VBB output if utilized.

Translators, Level Shifters Selection Notes

Select this component when space-constrained designs require translating LVPECL clock or data signals to LVTTL. It serves as a pin-for-pin replacement for MC100EPT21D/DT variants. Consider the 8-pin MSOP package for minimal footprint requirements compared to standard SOIC options.

Translators, Level Shifters Part Context

This part belongs to the SY100EPT series of voltage level translators designed for high-speed signal conversion. It utilizes Micrel's ECL Pro technology to provide low skew and low power operation. The device is specifically engineered for applications requiring reliable translation between Low Voltage Positive ECL and Low Voltage Transistor-Transistor Logic standards.

Translators, Level Shifters FAQ

What happens to the output if the 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, which forces the Q output low to provide added stability.

How should the VBB output be handled if used?

If the VBB output is utilized, it should be bypassed to VCC with a 0.01 µF capacitor.
