MC10EP195FA

Overview

The MC10EP195FA is a programmable delay chip from onsemi designed for clock deskewing and timing adjustment. It provides variable delay of differential NECL/PECL input transitions with 10 ps increments. The device supports PECL mode (VCC = 3.0 V to 3.6 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = -3.0 V to -3.6 V). Key electrical parameters include a maximum input clock frequency exceeding 1.2 GHz, a programmable range of 0 ns to 10 ns, and a delay range of 2.2 ns to 12.2 ns. It features safety clamps on inputs, an open input default state, and D[10:0] pins accepting ECL, LVCMOS, or LVTTL inputs.

Feature Summary

• Programmable delay functionality for precise clock deskewing and timing adjustments
• Supports both PECL and NECL operating modes with flexible voltage configurations
• Includes safety clamps on inputs and an open input default state for reliability

Applications

• Clock deskewing in high-speed digital systems
• Timing adjustment in communication infrastructure
• Precision delay generation in test and measurement equipment

Procurement Notes

Verify the specific suffix 'FA' against official datasheets to confirm package type and RoHS status. Check for active manufacturing status as older suffixes may be obsolete. Confirm supply chain availability through authorized distributors only. Ensure compatibility with required voltage levels and input logic families before procurement.

Selection Notes

Select this component when precise programmable delay is required for differential ECL signals. Consider the 10 ps increment resolution and 1.2 GHz frequency capability. Verify that the 3.3 V supply requirement matches the system design. Evaluate if temperature compensation is needed, noting that the 100 series typically includes it.

Part Context

The MC10EP195FA belongs to the MC10/100EP195 family of programmable delay chips. This series is engineered for high-frequency applications requiring accurate timing control. The device integrates multiple delay taps controlled by digital inputs to adjust signal propagation time dynamically.

Replacement Considerations

MC10EP195FAR2G is listed as a direct replacement for discontinued variants. Verify pinout and electrical specifications match before substitution.
