MC100EP91DWG

Translators, Level Shifters Overview

The MC100EP91DWG is a triple any-level positive input to NECL output translator manufactured by onsemi. It accepts LVPECL, LVTTL, LVCMOS, HSTL, CML, or LVDS signals and translates them to differential NECL outputs (-3.0 V to -5.5 V). The device operates with three power rails: VCC (2.375 V to 3.8 V), VEE (-3.0 V to -5.5 V), and GND (0 V). Key electrical parameters include a typical propagation delay of 500 ps, maximum input clock frequency exceeding 2.0 GHz, and maximum input data rate exceeding 2.0 Gb/s. It is housed in a 20-pin SOIC-Wide package.

Translators, Level Shifters Feature Summary

• Accepts multiple input logic levels including LVPECL, LVTTL, LVCMOS, HSTL, CML, and LVDS for versatile interface compatibility.
• Translates positive input signals to differential NECL outputs suitable for high-speed negative voltage environments.
• Features internal pull-down and pull-up resistors that force Q outputs to a low state when inputs are open or at ground.
• Includes an internally generated VBB reference voltage pin available for single-ended input biasing or AC coupling rebiasing.

Translators, Level Shifters Applications

• Interfacing between different logic families in high-speed digital systems
• Clock distribution networks requiring translation from positive to negative ECL levels
• Data communication equipment utilizing LVDS or CML sources driving NECL receivers

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the MC100EP91 family includes both SOIC-20 and QFN-24 variants. Confirm RoHS compliance status and check for discontinuation notices, as certain suffixes like MNG may be discontinued. Ensure the selected part matches the required thermal management needs for the chosen package style during integration.

Translators, Level Shifters Selection Notes

Select this component when interfacing positive logic standards such as LVCMOS or LVPECL with negative ECL (NECL) loads. Ensure the design supports the required three-power-rail configuration (VCC, VEE, GND). Verify that the application environment stays within the specified operating temperature range of -40°C to +85°C and that power supply decoupling meets the datasheet requirements for stability.

Translators, Level Shifters Part Context

The MC100EP91 belongs to the 100EP series of high-speed ECL translators from onsemi. This series focuses on bridging gaps between various modern positive logic standards and traditional negative ECL architectures. The DWG suffix specifically denotes the 20-pin Wide Small Outline Integrated Circuit (SOIC-WB) package variant, distinguishing it from other package options within the same functional family.
