MC100EP16VSDTG

Specialty Logic Overview

The MC100EP16VSDTG is a single-channel differential receiver/driver from the onsemi MC100EP series, housed in an 8-lead TSSOP package. It operates with a supply voltage range of 3.0 V to 5.5 V (PECL mode) or -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 operating conditions.

Specialty Logic Feature Summary

• Features a dedicated VCTRL input pin that allows for variable control of the output signal amplitude.
• Includes an internally generated reference voltage (VBB) pin designed for biasing AC-coupled inputs or unused differential inputs.
• Incorporates temperature compensation circuitry to maintain stable performance across the industrial temperature range.
• Provides 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 interfaces
• Clock distribution networks requiring adjustable signal swing
• Differential signaling systems utilizing PECL or NECL logic families

Specialty Logic Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-8 package variant as listed in the ordering information table. Confirm RoHS compliance status by checking the 'G' suffix designation if lead-free packaging is required. Ensure the application design accounts for the thermal resistance characteristics associated with the TSSOP-8 footprint during operation.

Specialty Logic Selection Notes

Select this component when variable output amplitude control is necessary within a high-speed ECL environment. It serves as a functional equivalent to the standard EP16 but adds the VCTRL capability. Consider the 220 ps propagation delay and >4 GHz frequency limits against system timing requirements. Verify compatibility with existing PECL or NECL power supply architectures before integration.

Specialty Logic Part Context

This device belongs to the MC100EP family of 3.3V/5V ECL differential receivers and drivers. The family is characterized by high-speed performance and temperature compensation. The MC100EP16VSDTG specifically represents the single-channel variant with variable swing capabilities, distinct from quad-channel or fixed-swing counterparts in the same product line.

Specialty Logic Replacement Considerations

The datasheet identifies the MC100EP16 as a functionally equivalent device lacking the variable swing feature. No other direct substitute part numbers are explicitly confirmed in the provided documentation.

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 amplitude. When VCTRL equals VCC, the output reaches minimum amplitude. If left open, it pulls down to VEE for 100% amplitude.

What is the purpose of the VBB pin?

VBB is an internally generated reference voltage used to bias AC-coupled inputs or serve as a switching reference for unused differential inputs. It must be decoupled with a 0.01 µF capacitor if utilized.

What happens to the output if the differential inputs are left open?

If the inputs are left open or connected to VEE, the internal input pulldown forces the Q output to default to a LOW state.
