SY100E196JC

Overview

The SY100E196JC is a programmable delay chip (PDC) designed for accurate differential ECL input edge placement. It provides a digitally selectable delay range of approximately 2ns with a resolution of about 20ps using seven address inputs. An analog FTUNE input allows further linear adjustment to enhance resolution. The device features an extended VEE operating range from –4.2V to –5.5V and supports cascading via internal circuitry. It operates at frequencies greater than 1GHz and includes on-chip cascade logic, a 75kΩ input pulldown resistor, and is available in a 28-pin PLCC package.

Feature Summary

• Programmable delay with digital step resolution and analog fine-tuning capability
• Internal cascade architecture for expanding delay range without external gating
• Extended negative supply voltage operating range for flexible power configurations
• High-bandwidth performance suitable for precise differential signal timing

Applications

• Differential ECL input edge placement applications
• Clock deskewing and timing adjustment systems
• Multi-device cascaded delay line architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead finish specifications. Ensure compatibility with existing system voltage levels, particularly the extended VEE range requirements. Confirm that the component meets all environmental operating temperature ranges required for the intended deployment scenario before finalizing procurement orders.

Selection Notes

Select this component when precise differential ECL timing control is required with a programmable range around 2ns. Consider the FTUNE pin if sub-20ps resolution is necessary through analog adjustment. Evaluate the need for cascading multiple units by checking the D7 cascade input availability. Ensure the design accommodates the 28-pin PLCC footprint and the specified power supply constraints.

Part Context

The SY100E196JC belongs to the Precision Edge series of programmable delay chips manufactured by Micrel. It is functionally compatible with Motorola MC10E/100E196 devices. The JC suffix denotes the commercial temperature range variant housed in a 28-pin PLCC package with Sn-Pb lead finish. This part is distinct from the SY100EP196V which offers a wider delay range and different packaging options.

Replacement Considerations

The datasheet states full compatibility with Motorola MC10E/100E196. Verify pinout and electrical characteristics match exactly before substitution. No other specific substitute part numbers are documented in the provided source material.
