SY605JC

Overview

The SY605JC is an ECL-compatible programmable timing edge vernier manufactured by Micrel-Synergy. It generates precise time delays programmed via an 8-bit code loaded through a WRITE input. Fabricated in the ASSET bipolar process, it supports retriggering up to 125MHz with a delay span adjustable from 4ns to 40ns. The device features differential TRIGGER and WRITE inputs, producing a differential output pulse typically 3.5ns wide. It operates within a supply voltage range of -5.7V to -4.2V and consumes approximately 350mW. The component is available in a 28-pin plastic J-lead package.

Feature Summary

• Supports true 125MHz retrigger rate with 15ps delay resolution
• Features differential TRIGGER and WRITE inputs for precise control
• Offers externally adjustable delay spans ranging from 4ns to 40ns
• Provides less than ±1 LSB timing accuracy

Applications

• Automatic Test Equipment (ATE) for precise timing edge placement
• Instrumentation systems requiring accurate signal delay
• Communications applications needing programmable timing edges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and temperature range. The SY605JC designation corresponds to the commercial operating range in a 28-lead PLCC package. Ensure compatibility with existing ECL logic levels and power supply requirements before procurement.

Selection Notes

Select this component when high-speed programmable delay is required with ECL interface compatibility. Consider the 8-bit resolution and adjustable span for application needs. Verify that the system can provide the necessary differential trigger signals and appropriate current reference settings for the desired delay span.

Part Context

The SY605JC belongs to the SY605 family of timing verniers produced by Micrel-Synergy. It utilizes proprietary ASSET bipolar technology to achieve ultra-fast performance and lower power dissipation compared to competing technologies. The device is pin-compatible with the Bt605 model, facilitating potential design upgrades or replacements.

Replacement Considerations

The SY605JC is pin-compatible with the Bt605 model. When substituting, verify that the alternative device maintains ECL compatibility and meets the required 125MHz retrigger rate specifications.
