MC100EP16VSDG

Specialty Logic Overview

The MC100EP16VSDG is a 3.3V/5V ECL differential receiver/driver with variable output swing, manufactured by onsemi in an SOIC-8 package. It features a VCTRL pin to control output amplitude from maximum to minimum. Operating parameters include a typical propagation delay of 220 ps and a maximum toggle frequency exceeding 4 GHz. The device supports PECL mode (VCC 3.0V to 5.5V, VEE=0V) and NECL mode (VCC=0V, VEE -3.0V to -5.5V). Power supply current ranges from 30 mA to 48 mA depending on temperature. It includes internal input pull-down/pull-up resistors, open-input default states, and meets JEDEC latchup specifications.

Specialty Logic Feature Summary

• Variable output amplitude controlled via the VCTRL pin referenced to VCC
• Temperature compensation included within the 100 series design
• Internal reference voltage generation at the VBB pin for biasing or single-ended switching
• Open input default state forces Q output LOW when inputs are floating or at VEE

Specialty Logic Applications

• High-speed data transmission systems requiring adjustable signal levels
• Interfacing with high-frequency sources where output swing optimization is necessary
• PECL and NECL logic circuits operating across wide voltage ranges
• Applications utilizing AC-coupled inputs requiring specific biasing via VBB

Specialty Logic Procurement Notes

Verify the ordering suffix 'DG' corresponds to the Pb-free SOIC-8 variant as specified in the manufacturer's ordering information. Confirm that the required package type matches the D suffix designation. Ensure procurement channels provide documentation verifying RoHS compliance and lead-free status. Cross-reference the part number against the latest datasheet revision to confirm functional equivalence and availability of technical support resources.

Specialty Logic Selection Notes

Select this component when variable output swing capability is required compared to standard fixed-swing receivers. Consider the thermal resistance characteristics if operating near maximum ambient temperatures. Evaluate the VCTRL control circuitry requirements, noting that leaving the pin open defaults to maximum amplitude. Verify compatibility with existing PECL or NECL power supplies and ensure proper decoupling for the VBB pin if utilized for biasing purposes.

Specialty Logic Part Context

This device belongs to the MC100EP family of ECL logic components, specifically designed for high-speed applications. It is functionally equivalent to the MC10EP16 but includes the additional VCTRL feature for amplitude control. The 100 series distinguishes itself through integrated temperature compensation, ensuring stable performance across the industrial temperature range. It serves as a specialized interface solution for differential signaling environments.

Specialty Logic Replacement Considerations

The MC10EP16 serves as a functional substitute lacking the variable swing feature. The MC100EP16 provides identical functionality without the VCTRL pin. Substitutes must be verified for package compatibility and electrical parameter alignment, particularly regarding propagation delay and power supply requirements.

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. When VCTRL equals VCC, the output reaches minimum swing. Leaving the pin open internally pulls it to VEE, resulting in 100% output amplitude.

What is the purpose of the VBB pin?

The VBB pin provides an internally generated reference voltage. It can be used to bias unused differential inputs for single-ended operation or to rebias AC-coupled inputs. It requires decoupling via a 0.01 µF capacitor if used, and should remain open if not utilized.

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

If the differential inputs (D, D) are left open or pulled to VEE, the internal input clamping circuitry forces the Q output to a LOW state. This ensures a defined default state in the absence of active signals.
