MC100EP16VTDR2G

Specialty Logic Overview

The MC100EP16VT is a differential receiver functionally equivalent to the 100EP16, featuring input pins that control output amplitude and provide an internal termination network. It operates in PECL mode with VCC from 3.0V to 5.5V (VEE = 0V) or NECL mode with VEE from -3.0V to -5.5V (VCC = 0V). Key electrical parameters include a typical propagation delay of 220ps, a maximum toggle frequency exceeding 4GHz, and a power supply current ranging from 30mA to 48mA depending on voltage and temperature. The device includes a 50-ohm internal termination resistor at pin 4.

Specialty Logic Feature Summary

• Features a VCTRL input pin referenced to VCC for controlling output swing amplitude, allowing adjustment from minimum to maximum levels.
• Includes an internal 50-ohm termination network accessible via the VTT input pin for 50-ohm line impedance environments.
• Provides open input default state functionality where the VCTRL pin defaults low when left open, operating as a standard EP16 with 100% output amplitude.
• Incorporates temperature compensation within the 100 Series design to ensure stable performance across varying thermal conditions.

Specialty Logic Applications

• High-speed data transmission systems requiring variable output swing control
• Clock distribution networks utilizing ECL logic families
• Interfacing applications between different voltage domains using PECL or NECL standards

Specialty Logic Procurement Notes

Verify the specific package suffix required for your design, such as D for SO-8 or DT for TSSOP-8, as these determine physical dimensions and mounting style. Confirm whether tape and reel quantities are needed for automated assembly processes. Ensure compatibility with existing PCB footprints by checking the case outline specifications provided in the datasheet before finalizing component selection.

Specialty Logic Selection Notes

Select this component when variable output amplitude control is necessary alongside high-speed differential signaling capabilities. Consider the internal termination feature if board space constraints prevent adding external resistors. Evaluate the operating voltage range to ensure alignment with either PECL or NECL system requirements. Verify thermal management needs based on the junction-to-ambient resistance values provided for your chosen package type.

Specialty Logic Part Context

This device belongs to the MC100EP family of ECL receivers and drivers manufactured by onsemi. It serves as a specialized variant offering enhanced flexibility through adjustable output swing and integrated termination, distinguishing it from standard fixed-amplitude counterparts like the basic MC100EP16. The series is designed for robust performance in demanding digital communication environments.

Specialty Logic Replacement Considerations

The MC100EP16VT is functionally equivalent to the MC100EP16 but adds variable swing and termination features. Direct substitutes may include other members of the MC100EP series, though specific pinout and feature differences must be verified against the target application requirements to ensure compatibility.

Specialty Logic FAQ

How does the VCTRL pin affect the output amplitude?

The VCTRL pin controls the output amplitude relative to VCC. When left open, it pulls down to VEE, resulting in 100% output amplitude. Adjusting the voltage between VBB and VCC allows modulation of the swing from minimum to maximum levels.

What is the purpose of the VTT pin?

The VTT pin provides access to an internal 50-ohm termination network designed for use in 50-ohm line impedance environments, simplifying circuit design by eliminating the need for external termination resistors.
