SY10E195JC

Overview

The SY10E195JC 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 2ns delay range, ≈20ps digital step resolution, and >1GHz bandwidth. It includes on-chip cascade circuitry, a 75KkΩ input pulldown resistor, and operates in a 28-pin PLCC package.

Feature Summary

• Provides digitally selectable variable delay for differential ECL transitions
• Features internal cascade logic for expanding programmable delay range without external gating
• Offers fine resolution via modified gate delays in the first two elements

Applications

• Clock deskewing
• Timing adjustment

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or discontinued. Confirm RoHS compliance status and lead finish type (Sn-Pb vs Matte-Sn) based on specific ordering suffixes. Ensure environmental operating conditions match application requirements before procurement.

Selection Notes

Select the SY10E195JC when precise programmable delay is required for high-frequency differential signals. Consider the 28-pin PLCC package constraint and verify voltage compatibility with the extended VEE range. Evaluate cascading needs if delay ranges exceed single-device capabilities.

Part Context

This component belongs to the Precison Edge® family of programmable delay chips. It is fully compatible with Motorola MC10E/100E195 equivalents. The device utilizes purely differential ECL gate delays to achieve high-frequency operation while maintaining significant output swing.

Replacement Considerations

The SY10E195JC is fully compatible with the Motorola MC10E195. Verify pinout and electrical specifications against alternative sources to ensure functional equivalence in existing designs.
