MC10E196FN

Overview

The MC10E196FN is a programmable delay chip (PDC) designed for accurate differential ECL input edge placement. It operates in PECL mode with VCC from 4.2 V to 5.7 V and NECL mode with VEE from -4.2 V to -5.7 V. The device provides a worst-case delay range of 2.0 ns with approximately 20 ps per step resolution. An analog FTUNE input allows linear voltage adjustment to further reduce the minimum resolution. It features on-chip cascade circuitry for increased programmable range using only one additional address line per cascaded device. The component is housed in a PLCC-28 package.

Feature Summary

• Programmable delay chain with digital select inputs and an analog FTUNE pin for fine-tuning resolution
• On-chip cascade logic enabling multiple devices to be linked without external gating
• Internal VBB reference voltage output for single-ended input switching or AC coupling rebiasing
• Temperature compensated architecture ensuring stable delay performance across operating ranges

Applications

• Differential ECL input edge placement applications
• Clock deskewing and timing adjustment circuits
• High-speed data synchronization systems requiring precise delay control

Procurement Notes

Verify the specific ordering suffix to confirm package type and environmental compliance. The 'FN' suffix indicates a standard PLCC-28 package, while 'FNG' denotes a lead-free variant. Confirm that the required supply voltage configuration matches either PECL or NECL operational modes before procurement. Ensure all power pins are externally connected to guarantee proper operation as specified in the datasheet.

Selection Notes

Select the MC10E196FN when a programmable delay range up to 2.0 ns is required with approximately 20 ps resolution. Choose this component over the MC10E195 if analog fine-tuning via the FTUNE pin is necessary. Consider the MC100E196 series if temperature compensation is a critical requirement for the application environment. Verify that the PLCC-28 package fits the available PCB footprint constraints.

Part Context

The MC10E196 belongs to the MC10E/100E196 family of programmable delay chips manufactured by onsemi. It is part of the 10E series logic products designed for high-speed ECL applications. The device serves as a specialized timing element within clock distribution networks, offering flexibility through digital tap selection and analog tuning capabilities not present in earlier fixed-resolution delay lines.

Replacement Considerations

The MC10E195 is a related component but lacks the FTUNE analog input feature. The MC100E196 offers temperature compensation which may be preferred for wider thermal ranges. No direct cross-model substitutes with identical pinouts and functions are documented.
