MC100EP195FAG

Overview

The MC100EP195FAG is a programmable delay chip from onsemi, designed for clock deskewing and timing adjustment in high-speed digital systems. It provides variable delay of differential NECL/PECL input transitions with a typical maximum input clock frequency exceeding 1.2 GHz. The device features a programmable delay range of 0 ns to 10 ns with 10 ps increments. It operates in PECL mode with VCC between 3.0 V and 3.6 V (VEE = 0 V) or in NECL mode with VCC at 0 V and VEE between -3.0 V and -3.6 V. The component includes temperature compensation, open input default state protection, and safety clamps on inputs.

Feature Summary

• Programmable delay capability with 10 ps resolution for precise timing adjustments
• Supports both NECL and PECL logic families for flexible interface compatibility
• Integrated temperature compensation ensures stable performance across operating conditions
• Built-in safety clamps and open input default states enhance signal integrity

Applications

• Clock deskewing in high-speed data communication systems
• Timing adjustment in automated test equipment (ATE)
• Signal synchronization in complex digital logic circuits

Procurement Notes

Verify the specific suffix 'FAG' against official datasheets to confirm package type and RoHS compliance status. Ensure that ordering requirements match the manufacturer's current production status, as lead times and availability may vary. Confirm that the voltage supply levels align with the specified PECL or NECL operating ranges before integration.

Selection Notes

Select this component when precise sub-nanosecond delay tuning is required for differential ECL signals. Consider the 10 ps increment resolution for fine-tuning applications. Evaluate the power supply constraints, as the device requires specific voltage configurations for PECL or NECL modes. Verify that the operating temperature range meets the environmental requirements of the target system.

Part Context

The MC100EP195 series belongs to onsemi's high-frequency ECL programmable delay line family. These devices are engineered for skew management in systems requiring tight timing control. The EP195 variant specifically offers a standard programmable range without additional fine-tune pins found in related models like the EP196A.

Replacement Considerations

The MC100EP195BMNG is a direct functional substitute within the same series. Verify pinout compatibility and package dimensions (QFN-32 vs LQFP-32) during replacement. Check if the alternative package affects thermal performance or board layout constraints.
