SY604JC

Overview

The SY604JC is an ECL-compatible timing vernier delay generator manufactured by Microchip Technology. It features a true 125MHz retrigger rate and produces differential output pulses with a typical width of 3.5ns. The device utilizes an 8-bit code loaded concurrently with the trigger to program edge delay, achieving a resolution of 15.7ps per step at minimum span. The externally adjustable delay span ranges from 4ns to 40ns. It operates within a commercial temperature range of 0°C to +85°C using a -5.7V to -4.2V supply.

Feature Summary

• Supports high-speed retriggering up to 125MHz for precise timing applications
• Provides differential trigger inputs and differential outputs for signal integrity
• Offers programmable delay via 8-bit input code latched on the trigger edge
• Features externally adjustable delay spans ranging from 4ns to 40ns

Applications

• Automatic Test Equipment (ATE) for precise timing edge placement
• Instrumentation systems requiring accurate delay generation
• Communications equipment utilizing ECL logic families

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and operating temperature range. Ensure that the power supply voltage levels align with the specified -5.7V to -4.2V operating range. Confirm compatibility with existing ECL logic interfaces before finalizing procurement orders.

Selection Notes

Select this component when differential triggering and high-speed retrigger capabilities are required. Ensure the design accommodates the necessary external components for setting the delay span current reference. Verify that the system environment remains within the specified commercial temperature limits during operation.

Part Context

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

Replacement Considerations

The SY604JC is pin-compatible with the Bt604. Substitution should be verified against the latest datasheet specifications to ensure electrical parameter alignment.
