SY604JC-TR

Overview

The SY604JC-TR is an ECL-compatible programmable timing edge vernier manufactured by Microchip Technology in a 28-pin PLCC package. It functions as a delay generator with a maximum trigger rate of 125MHz and a minimum delay span of 4ns. The device utilizes an 8-bit code loaded concurrently with the trigger to set the time delay, achieving a resolution of 15.7ps per step at the minimum span. Typical power dissipation is 350mW, and it operates within a commercial temperature range.

Feature Summary

• Supports retriggering speeds up to 125MHz
• Features differential TRIGGER inputs for precise timing edge placement
• Provides externally adjustable delay spans from 4ns to 40ns
• Compatible with 10K H ECL logic families

Applications

• Automatic Test Equipment (ATE) for precise timing edge placement
• Instrumentation applications requiring programmable delays
• Communications systems utilizing ECL logic

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering suffix matches the required package type and operating temperature range. Review the datasheet for absolute maximum ratings and thermal management requirements before integration into production designs.

Selection Notes

Select this component when designing high-speed ECL circuits requiring programmable delay generation. Ensure the application supports the -5.7V to -4.2V VEE supply range and accommodates the typical 350mW power dissipation. Verify that the 125MHz maximum trigger rate meets the system's timing requirements.

Part Context

This part belongs to the SY604 family of timing verniers produced by Micrel-Synergy, now under Microchip Technology. It is fabricated using the proprietary ASSET bipolar process, which enables ultra-fast performance and lower power dissipation compared to competing technologies. The device is pin-compatible with the Bt604.

Replacement Considerations

The SY604JC-TR is pin-compatible with the Bt604. Substitution should be verified against the original design specifications to ensure compatibility with existing ECL logic levels and power supply configurations.
