SY10E195JZ-TR

Overview

The SY10E195JZ-TR is a programmable delay chip (PDC) designed for clock deskewing and timing adjustment. It provides variable delay of a differential ECL input transition with an extended VEE range of –4.2V to –5.5V. The device features approximately 20ps digital step resolution and supports frequencies greater than 1GHz. It includes on-chip cascade circuitry, a 75KkΩ input pulldown resistor, and operates in a 28-pin PLCC package.

Feature Summary

• Provides variable delay for differential ECL input transitions
• Features approximately 20ps digital step resolution
• Includes internal cascade circuitry for expanded range
• Fully compatible with Motorola MC10E/100E195

Applications

• Clock deskewing
• Timing adjustment

Procurement Notes

Verify the component status as the datasheet indicates it is not recommended for new designs. Confirm that the JZ suffix corresponds to the Pb-Free package variant with a Matte-Sn finish. Ensure the TR suffix matches the required Tape and Reel packaging format for your assembly process.

Selection Notes

Select this part when precise differential ECL signal delay is required within a 2ns range. Consider cascading multiple units if delays exceeding the single-device maximum are necessary. Verify compatibility with the –4.2V to –5.5V VEE supply range and ensure the 28-pin PLCC footprint fits the design constraints.

Part Context

This component belongs to the Precision Edge series of programmable delay chips originally manufactured by Micrel, Inc., which was later acquired by Microchip Technology. The product line focuses on high-speed timing control solutions utilizing ECL technology for applications requiring fine-grained delay adjustments.

Replacement Considerations

The datasheet states full compatibility with the Motorola MC10E195 and MC100E195. These parts serve as direct functional equivalents for system upgrades or sourcing alternatives.
