MC100E196FNR2G

Overview

The MC100E196FNR2G is a 5V/EnECL Programmable Delay Chip (PDC) designed for accurate differential ECL input edge placement. It features a digitally selectable delay range of approximately 2.0 ns with a resolution of about 20 ps per step, enhanced by an analog FTUNE linear ramp input for finer adjustment. The device operates in PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) or NECL mode (VCC = 0 V, VEE = −4.2 V to −5.7 V). It includes on-chip cascade circuitry for extended programmable ranges and internal 50 kΩ pulldown resistors. Packaged in PLCC-28, it supports temperatures from 0°C to +85°C.

Feature Summary

• Programmable delay chip with digital resolution of approximately 20 ps and analog FTUNE input for tighter resolution
• On-chip cascade circuitry allows expansion of programmable range without external gating
• Supports both PECL and NECL operating modes with internal 50 kΩ pulldown resistors

Applications

• Very accurate differential ECL input edge placement applications
• Clock deskewing and timing adjustment in high-speed systems
• Cascading multiple PDCs for increased programmable delay range

Procurement Notes

Verify the specific ordering suffix 'R2G' corresponds to the tape and reel packaging format as documented in the manufacturer's ordering information. Confirm that the component meets RoHS compliance requirements if applicable to the design specifications. Ensure the procurement channel provides valid traceability for the Pb-Free package designation.

Selection Notes

Select this component when precise differential ECL signal timing adjustments are required. The inclusion of the FTUNE pin distinguishes it from the E195 model by providing analog tunability for sub-20 ps resolution. Consider the cascading capability via the D7 input if the application demands a programmable range exceeding the single-device maximum of 2.0 ns.

Part Context

The MC100E196 belongs to the 100 Series of ECLinPS devices, which feature temperature compensation. It is part of the MC10E/100E196 family, sharing architecture with the MC10E196 but optimized for the 100 Series specifications. The device utilizes a PLCC-28 package (Case 776) and contains 425 transistors.

Replacement Considerations

The MC10E196 serves as a functional equivalent within the same family, differing primarily in series-specific electrical characteristics. For applications requiring similar functionality without the analog FTUNE fine-tuning capability, the MC10E195 may be considered, though it lacks the linear ramp input.
