SY100E195JI

Overview

The SY100E195JI is a programmable delay chip (PDC) designed for clock de-skewing 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, >1GHz bandwidth, and up to 2ns delay range. It includes on-chip cascade circuitry and a 75KkΩ input pulldown resistor. The component operates within a temperature range of -40°C to +85°C and is housed in a 28-pin PLCC package.

Feature Summary

• Provides digitally selectable variable delay for differential ECL transitions using internal gate chains.
• Features on-chip cascade logic allowing multiple devices to be linked without external gating.
• Includes a 7-bit latch controlled by a high signal on the latch enable pin.

Applications

• Clock de-skewing
• Timing adjustment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm lead finish and environmental compliance. Confirm that the industrial temperature grade matches the design requirements. Check for any process change notifications or lifecycle status updates prior to procurement.

Selection Notes

Select this component when precise digital control over differential ECL signal propagation delay is required. Ensure the system power supply aligns with the specified VEE range. Consider cascading capabilities if the total required delay exceeds the single-device maximum range.

Part Context

This part belongs to the Precison Edge® family of programmable delay chips. It is fully compatible with the Motorola MC10E/100E195 specifications. The device utilizes purely differential ECL gate delays to maintain high-frequency operation while providing fine resolution.

Replacement Considerations

The SY100E195JI is fully compatible with the Motorola MC10E/100E195. Verify pinout and electrical characteristics match before substitution.
