MC100EP90DTR2

Translators, Level Shifters Overview

The MC100EP90DTR2 is a triple ECL to LVPECL/PECL translator manufactured by onsemi. It receives differential LVECL or ECL signals and translates them to differential LVPECL or PECL output signals. The device operates with VCC supplies from 3.0 V to 5.5 V, VEE supplies from -3.0 V to -5.5 V, and GND at 0 V. It features a typical propagation delay of 260 ps and supports maximum frequencies exceeding 3 GHz. The component includes temperature compensation, an open input default state where Q outputs default LOW, and safety clamps on inputs. It utilizes a TSSOP-20 package.

Translators, Level Shifters Feature Summary

• Translates differential LVECL or ECL signals to differential LVPECL or PECL outputs
• Includes a VBB output for interfacing with single-ended LVECL or ECL signals
• Features fully differential design with internal temperature compensation
• Provides safety clamps on inputs and defaults Q outputs LOW when inputs are open

Translators, Level Shifters Applications

• High-speed signal translation between ECL and LVPECL/PECL domains
• Interfacing single-ended LVECL or ECL sources using the VBB reference pin
• Systems requiring robust input protection and defined default states

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation. The datasheet indicates that certain variants within the MC10EP90 family may be discontinued and not recommended for new designs. Confirm availability status directly with authorized distributors or onsemi representatives before finalizing procurement plans to ensure compliance with current production lifecycles.

Translators, Level Shifters Selection Notes

Select this component when translating differential ECL or LVECL signals to LVPECL or PECL standards. Ensure the design accommodates three distinct power rails: VCC (3.0 V to 5.5 V), VEE (-3.0 V to -5.5 V), and GND. Verify that the application requires the specific voltage supply ranges and thermal characteristics supported by the TSSOP-20 package configuration.

Translators, Level Shifters Part Context

This part belongs to the MC10/100EP90 series of translators designed for high-frequency applications. It serves as a bridge between legacy ECL logic families and modern LVPECL/PECL interfaces. The device integrates safety features such as input clamping and defined open-input states to enhance system reliability in high-speed digital environments.

Translators, Level Shifters Replacement Considerations

The MC10EP90DTG variant is listed as discontinued and not recommended for new designs. Consult onsemi representatives for current alternatives if sourcing the MC10EP90DTR2G variant proves difficult. Verify functional compatibility and pinout alignment before substituting any other translator devices.

Translators, Level Shifters FAQ

How should the VBB output be used for single-ended inputs?

Connect the VBB output to the D input. The active signal then drives the D input. When used, the VBB output must be bypassed to ground with a 0.01 μF capacitor.

What is the default state of the outputs if inputs are left open?

When inputs are open or at VEE, the Q outputs will default to a LOW state.

What are the required power supply connections for operation?

The device requires three power rails: VCC connected to the positive supply, VEE connected to the negative supply, and GND connected to ground.
