MC10E196FNG

Overview

The MC10E196FNG is a 5V/EnECL Programmable Delay Chip (PDC) designed for accurate differential ECL input edge placement. It features a digitally selectable resolution of approximately 20 ps and an analog FTUNE input for finer adjustment. The device operates in PECL mode with VCC from 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VEE from -4.2 V to -5.7 V (VCC = 0 V). It provides a worst-case delay range of 2.0 ns, supports cascading via the D7 pin, and includes internal 50 kΩ pulldown resistors. The component is housed in a PLCC-28 package.

Feature Summary

• Programmable delay chain with digital resolution and linear ramp fine-tuning
• On-chip cascade circuitry for expanding programmable range without external gating
• Internal reference voltage output (VBB) for single-ended inputs or AC coupling rebiasing
• ESD protection exceeding 1 kV Human Body Model and 75 V Machine Model

Applications

• Very accurate differential ECL input edge placement applications
• Clock deskewing and timing adjustment in high-speed systems
• Cascaded programmable delay line configurations

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance. The 'G' suffix indicates a lead-free package. Confirm that the required operating temperature range aligns with the specified 0°C to +85°C limits. Ensure power supply connections for all VCC, VCCO, and VEE pins are properly decoupled to guarantee stable operation.

Selection Notes

Select this component when precise programmable delay control is required for differential ECL signals. The inclusion of the FTUNE pin allows for sub-digital step resolution enhancement. Consider the cascading capability if the application demands a total delay range exceeding the single-device maximum. Verify compatibility with either PECL or NECL logic levels based on the system power supply configuration.

Part Context

This part belongs to the MC10E/100E series of ECLinPS programmable delay chips. It shares architectural similarities with the MC10E195 but adds the FTUNE analog input for improved resolution. The 100 Series variant offers temperature compensation, whereas the standard 10E Series does not. Both variants utilize the same PLCC-28 footprint and pinout assignments.

Replacement Considerations

The MC10E195 serves as a base model without the FTUNE fine-tuning feature. For applications requiring temperature compensation, the MC100E196 is the direct equivalent within the 100 Series. No other cross-model replacements are explicitly documented in the provided datasheet.
