SY100EPT21LZC

Translators, Level Shifters Overview

The SY100EPT21LZC 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 24mA LVTTL output current and includes a VBB reference voltage output. It is housed in an 8-pin SOIC package (Z8-1) and supports commercial temperature ranges.

Translators, Level Shifters Feature Summary

• Supports differential LVPECL inputs for precision translation to general-purpose single-ended LVTTL outputs
• Includes a VBB output pin that allows flexible differential, single-ended, or AC-coupled interface configurations
• Provides added stability by forcing the Q output low under open input conditions

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 'ZC' against official documentation to confirm it denotes the commercial temperature range and Sn-Pb lead finish. Ensure compatibility with existing PCB footprints for the Z8-1 package. Confirm RoHS compliance status as standard versions may differ from Pb-Free variants.

Translators, Level Shifters Selection Notes

Select this component when a compact solution is required for translating high-speed differential clock or data signals. The flow-through pinout facilitates easy integration into designs needing minimal space and low power consumption. Consider the MSOP variant if a smaller footprint is necessary.

Translators, Level Shifters Part Context

This part belongs to the ECL Pro family of translators designed for low skew and low cost applications. It serves as a pin-for-pin replacement for legacy MC100EPT21D/DT devices, allowing for direct upgrades in systems requiring positive ECL 100K logic level compatibility.

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, 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.
