MC10EP195FAG

Overview

The MC10EP195FAG is a programmable delay chip manufactured by onsemi, designed for clock deskewing and timing adjustment applications. It provides variable delay for differential NECL/PECL input transitions with increments of 10 ps. The device operates within a PECL mode range of VCC = 3.0 V to 3.6 V with VEE = 0 V, or an NECL mode range of VCC = 0 V with VEE = −3.0 V to −3.6 V. It features a maximum input clock frequency exceeding 1.2 GHz typical, a programmable range of 0 ns to 10 ns, and a delay range of 2.2 ns to 12.2 ns. The component is housed in a QFN-32 package.

Feature Summary

• Provides precise programmable delay for differential signal transitions with 10 ps resolution steps.
• Supports both PECL and NECL operating modes with flexible power supply configurations.
• Includes safety clamps on inputs and an open input default state for reliable operation.
• Features a VBB output reference voltage and accepts ECL, LVCMOS, or LVTTL inputs for control data.

Applications

• Clock deskewing in high-speed digital systems
• Timing adjustment for differential clock distribution networks
• Skew management in communication infrastructure equipment

Procurement Notes

Verify the specific suffix 'FAG' against official datasheets to confirm package type and RoHS compliance status. Ensure that ordering information matches the exact part number required for the target application, as suffixes may indicate variations in packaging or material composition without altering the core electrical function.

Selection Notes

Select this component when precise sub-nanosecond delay tuning is required for differential clock signals. Consider the 10 ps increment resolution and the 1.2 GHz maximum input frequency capability. Verify compatibility with the system's logic levels (NECL vs. PECL) and ensure the QFN-32 package fits the PCB layout constraints.

Part Context

The MC10EP195 belongs to the MC10/100EP195 series of programmable delay chips from onsemi. This family is specifically engineered for skew management and timing alignment in high-frequency applications. The device integrates temperature compensation and multiple input logic compatibility to facilitate robust integration into complex timing architectures.
