SY10E196JC

Overview

The SY10E196JC is a programmable delay chip (PDC) designed for accurate differential ECL input edge placement. It provides an up to 2ns delay range with approximately 20ps digital step resolution and supports >1GHz bandwidth. The device operates within an extended VEE range of –4.2V to –5.5V and features on-chip cascade circuitry for expanded ranges. It includes a linear analog FTUNE input for tighter resolution, a 75KkΩ input pulldown resistor, and is housed in a 28-pin PLCC package.

Feature Summary

• Programmable delay chain with digital select inputs and analog FTUNE adjustment
• On-chip cascade logic for expanding delay range without external gating
• Extended negative supply voltage compatibility for ECL applications

Applications

• Differential ECL input edge placement
• Clock deskewing and timing adjustment
• High-speed signal path delay control

Procurement Notes

Verify component authenticity through authorized channels as the datasheet indicates this product is not recommended for new designs. Confirm that the specific ordering suffix matches the required lead finish and operating temperature range. Ensure the design accounts for the discontinued status by evaluating long-term availability constraints before finalizing procurement plans.

Selection Notes

Select the SY10E196JC when precise sub-nanosecond delay tuning is required for high-speed differential signals. The inclusion of the FTUNE pin allows for analog fine-tuning beyond the standard 20ps digital steps. Consider the cascading capability if the application requires a programmable range exceeding the single-device maximum of approximately 2ns.

Part Context

This component belongs to the Precision Edge series of programmable delay chips. It is fully compatible with the Motorola MC10E/100E196 specifications. The device utilizes a chain of gates and a linear ramp delay adjustment mechanism to achieve its specified performance characteristics in high-frequency environments.

Replacement Considerations

The SY10E196JC is fully compatible with the Motorola MC10E196 and MC100E196. Designers should verify pinout and electrical parameter alignment when substituting these equivalent parts from other manufacturers.
