MC100LVEL92DWR2G

Translators, Level Shifters Overview

The MC100LVEL92DWR2G is a triple PECL input to LVPECL output translator manufactured by onsemi. It requires three power rails: VCC connected to the standard 5V PECL supply, LVCC connected to the 3.3V LVPECL supply, and Ground connected to the system ground plane. Both VCC and LVCC must be bypassed to ground with 0.01 µF capacitors. The device features 500 ps propagation delays and operates within an LVPECL voltage range of 3.0 V to 3.8 V and a PECL voltage range of 4.5 V to 5.5 V. It includes internal input pulldown resistors and meets JEDEC latchup test specifications.

Translators, Level Shifters Feature Summary

• Translates standard PECL signals into differential LVPECL output signals using dual power supplies.
• Features temperature compensation for stable performance across varying environmental conditions.
• Includes internal input pulldown resistors to simplify external circuit design.
• Provides ESD protection exceeding 2 kV via Human Body Model and 200 V via Machine Model.

Translators, Level Shifters Applications

• High-speed signal processing requiring level translation between PECL and LVPECL domains
• Clock distribution systems interfacing different logic families
• Data acquisition systems utilizing mixed voltage standards

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix DWR2G corresponds to the SOIC-20 WB package in Tape & Reel format containing 1000 units per reel. Confirm RoHS compliance and Pb-Free status as specified in the datasheet. Ensure proper decoupling capacitors are included in the bill of materials for both VCC and LVCC pins to guarantee correct operation.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits operating at 5V PECL levels with those requiring 3.3V LVPECL outputs. The device supports a wide operating temperature range from -40°C to +85°C. Consider the requirement for separate power rails and the availability of the PECL VBB pin for reference voltage generation or AC coupling rebiasing during system architecture planning.

Translators, Level Shifters Part Context

This part belongs to the MC100LVEL92 series, which consists of triple translators designed for high-speed digital applications. The device utilizes a 20-pin Wide Body Small Outline Integrated Circuit (SOIC) package. It contains 247 transistors and is designed to meet strict reliability standards including UL 94 V-0 flammability ratings.

Translators, Level Shifters Replacement Considerations

The MC100LVEL92DWG serves as a tube-packaged alternative to the DWR2G variant. Both share identical electrical characteristics and functionality but differ in shipping packaging configuration.

Translators, Level Shifters FAQ

How should the PECL VBB pin be handled if not used?

When the PECL VBB pin is not utilized for single-ended input switching references or AC coupled input rebiasing, it should be left open.

What is the default state of the Q output if inputs are open?

The Q output will default to LOW if the inputs are open or fall below GND + 1.3 V.
