SY100EP196VTG

Overview

The SY100EP196VTG is a programmable delay line manufactured by Microchip Technology, housed in a 32-lead TQFP package. It supports PECL and NECL logic standards with operating supply voltages of 3.0V to 5.5V or -3.0V to -5.5V respectively. The device provides a programmable delay range from approximately 2.2ns to 12.2ns using a 10-bit digital control register, offering increments of about 10ps. An additional FTUNE pin allows for continuous fine-tuning of the delay within a 30ps range. The maximum operating frequency exceeds 2.5GHz.

Feature Summary

• Pin-for-pin compatible with ON Semiconductor MC100EP196
• Supports PECL, LVPECL, NECL, and LVNECL input signals
• Includes an analog FTUNE pin for continuous delay fine-tuning
• Features internal cascade logic for extending total delay range

Applications

• Clock de-skewing
• Timing adjustment
• Aperture centering

Procurement Notes

Verify that the ordering suffix 'TG' corresponds to the industrial temperature range (-40°C to +85°C) and the TQFP-32 package type as defined in the official datasheet. Confirm RoHS compliance status through the manufacturer's current documentation before procurement.

Selection Notes

Select this component when interfacing with high-speed ECL-based clock distribution networks requiring precise timing alignment. Ensure the system power supply matches the required PECL or NECL configuration. Verify that the control interface logic levels are compatible with the VCF and VEF pin settings.

Part Context

This part belongs to the SY100EP196V family of programmable delay chips designed for high-frequency applications. It serves as a direct replacement for the Micrel SY100EP196V and maintains compatibility with the onsemi MC100EP196 series for design continuity.

Replacement Considerations

Public confirmed substitutes include SY100EP196VTI and SY100EP196VTITR. These parts share identical functionality but differ in packaging format (Tube vs. Tape and Reel).

FAQ

How does the FTUNE pin affect the delay?

The FTUNE pin allows for continuous variation of the delay by approximately ±15ps. Adjusting the voltage at this pin enables fine-tuning beyond the discrete steps provided by the digital control register.

Can multiple SY100EP196V devices be cascaded?

Yes, an eleventh control bit and dedicated CASCADE outputs allow multiple devices to be cascaded. Each additional device effectively doubles the available delay range.

What logic standards are supported for the D inputs?

The D inputs can accept PECL, CMOS, or TTL level signals. The logic threshold is configured by connecting the VCF and VEF pins appropriately.
