MC100EP16VSDTR2G

Specialty Logic Overview

The MC100EP16VSDTR2G is a differential receiver/driver from the onsemi 100EP series, housed in an 8-TSSOP package. It operates within a supply voltage range of 3.0 V to 5.5 V with VEE at 0 V (PECL mode) or VCC at 0 V and VEE from -3.0 V to -5.5 V (NECL mode). The device features a typical propagation delay of 220 ps and supports maximum toggle frequencies exceeding 4 GHz. Power supply current ranges from 30 mA to 48 mA depending on temperature. It includes temperature compensation and provides a variable output swing controlled by the VCTRL pin.

Specialty Logic Feature Summary

• Features a dedicated VCTRL input pin that allows for precise control over the amplitude of the ECL data outputs.
• Incorporates internal temperature compensation to maintain stable performance across varying thermal conditions.
• Provides an internally generated reference voltage (VBB) suitable for biasing AC-coupled inputs or setting switching references.
• Includes open-input default states where the Q output defaults to LOW when inputs are left open or at VEE.

Specialty Logic Applications

• High-speed serial data transmission systems requiring adjustable signal amplitudes
• Clock distribution networks utilizing PECL or NECL logic families
• Differential signaling interfaces in telecommunications equipment
• Test and measurement instrumentation operating at gigahertz frequencies

Specialty Logic Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-8 package configuration required for your PCB layout. Confirm that the 'G' suffix indicates Pb-Free compliance if environmental regulations apply to your assembly process. Ensure the component matches the MC100EP16VS functional specification rather than standard variants lacking the variable swing feature.

Specialty Logic Selection Notes

Select this component when application requirements demand both high-speed differential signaling and dynamic output amplitude adjustment. It serves as a direct functional upgrade to the standard MC100EP16 for designs needing signal integrity optimization via swing control. Consider the 8-TSSOP package dimensions and ensure adequate thermal management given the junction-to-ambient resistance characteristics specified in the datasheet.

Specialty Logic Part Context

This part belongs to the MC100EP16 family of ECL receivers and drivers manufactured by onsemi. The 'VS' designation specifically identifies the variant equipped with the variable swing control capability, distinguishing it from the standard MC100EP16 which lacks the VCTRL pin. The 'DTR2G' suffix denotes the Tape & Reel packaging format in the TSSOP-8 case.

Specialty Logic FAQ

How does the VCTRL pin affect the output amplitude?

The VCTRL pin controls the output amplitude relative to VCC. When VCTRL is less than or equal to VBB, the output achieves maximum swing. As VCTRL approaches VCC, the output swing minimizes. If left open, the pin is internally pulled down to VEE, resulting in 100% output amplitude.

What is the function of the VBB pin?

VBB is an internally generated reference voltage available exclusively to this device. It can be used to bias AC-coupled inputs or serve as a switching reference for unused differential inputs in single-ended configurations. It must be decoupled with a 0.01 µF capacitor if utilized.
