SY100EPT21LZI

Translators, Level Shifters Overview

The SY100EPT21LZI is a single differential LVPECL-to-LVTTL translator manufactured by Micrel, Inc. 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 to operate within the industrial temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides translation between differential LVPECL input signals and general-purpose LVTTL outputs using a single 3.3V power supply.
• Features a flow-through pinout design that allows for direct plug-in replacement of legacy MC100EPT21 devices.
• Includes a VBB reference voltage output to support differential, single-ended, or AC-coupled interface configurations.

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix to confirm the package type and lead finish. The 'Z' suffix indicates an 8-pin SOIC package, while 'K' denotes an MSOP variant. Ensure the required tape and reel quantity matches the 'TR' designation if applicable. Confirm RoHS compliance status based on the final character of the part number before procurement.

Translators, Level Shifters Selection Notes

Select this component when minimal space, low power consumption, and cost efficiency are critical requirements. It is suitable for translating clock or data signals where low skew and high speed are necessary. Consider the SY89321L if an ultra-small footprint is preferred over the standard SOIC or MSOP packages offered by this device.

Translators, Level Shifters Part Context

This device belongs to the ECL Pro family from Micrel, Inc., designed for high-speed logic applications. The product line focuses on providing efficient voltage level translation solutions for systems requiring compatibility between different logic families. The manufacturer specializes in precision edge technology for signal integrity.

Translators, Level Shifters Replacement Considerations

The SY100EPT21LZI serves as a pin-for-pin, plug-in replacement for the MC100EPT21D/DT. Designers can directly substitute these legacy components without modifying the existing board layout or circuit connections.

Translators, Level Shifters FAQ

What happens to the output if the LVPECL 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 stability.

How should the VBB output be handled in a circuit design?

If the VBB output is utilized, it must be bypassed to VCC with a 0.01 µF capacitor to ensure proper operation and signal integrity.
