SY100EPT21LKI

Translators, Level Shifters Overview

The SY100EPT21LKI 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

• Supports differential LVPECL inputs for precision signal translation

• Includes VBB output for configurable interface options
• Ensures stability with Q output defaulting 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 that the specific ordering suffix 'KI' corresponds to the 8-pin MSOP package and Industrial temperature range (-40°C to +85°C). Confirm lead finish specifications if RoHS compliance or specific solderability requirements are mandatory for the assembly process. Ensure compatibility with existing PCB footprints designed for the K8-1 package type.

Translators, Level Shifters Selection Notes

Select this component when a low-skew, single-gate design is required for translating clock or data signals between LVPECL and LVTTL domains. It is suitable for applications where minimal space, low power consumption, and cost efficiency are critical constraints. Consider the flow-through pinout for simplified routing compared to other translators.

Translators, Level Shifters Part Context

This part belongs to the ECL Pro™ family of high-speed logic devices from Micrel (now Microchip Technology). It serves as a direct pin-for-pin replacement for the MC100EPT21DT. The device is designed to bridge legacy ECL standards with modern TTL levels using a compact surface-mount footprint.

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 level while the D input is pulled to ground. This forces the Q output LOW to provide added circuit stability.

How should the VBB output be handled if used?

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