SY100EP196VTG-TR

Overview

The SY100EP196VTG-TR is a programmable delay chip manufactured by Microchip Technology, operating in PECL or NECL modes. It provides a programmable delay range from approximately 2.2ns to 12.2ns with 10ps increments and a 30ps fine-tuning capability via the FTUNE pin. The device supports maximum frequencies exceeding 2.5GHz and accepts ECL, CMOS, or TTL control inputs. It is housed in a 32-pin TQFP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Programmable delay line with digital control for clock deskewing and timing adjustment
• Supports PECL, LVPECL, and NECL signal standards with flexible input logic compatibility
• Includes fine-tune voltage control for continuous delay variation
• Enables cascading of multiple units to extend total delay range

Applications

• Clock de-skewing in high-speed digital systems
• Timing adjustment for data signals
• Aperture centering applications

Procurement Notes

Verify the specific suffix 'VTG' against official documentation to confirm tape and reel packaging and industrial temperature grade. Confirm current availability status directly with authorized distributors as inventory levels fluctuate. Ensure compliance with RoHS directives if required for your application.

Selection Notes

Select this component when precise programmable delay between 2.2ns and 12.2ns is required at frequencies up to 2.5GHz. Consider cascading multiple units if delays beyond 12.2ns are needed. Ensure supply voltages match PECL (VCC=3.0V-5.5V) or NECL (VEE=-3.0V to -5.5V) requirements.

Part Context

This part belongs to the SY100EP series of ECL Pro® programmable delay chips. It is functionally compatible with the ON Semiconductor MC100EP196. The device is designed for high-speed timing applications requiring adjustable propagation delay with fine resolution.

Replacement Considerations

The ON Semiconductor MC100EP196 is a pin-for-pin, plug-in compatible alternative. Verify electrical characteristics and package dimensions before substitution.

FAQ

What is the minimum achievable delay?

The minimum delay is approximately 2.2ns due to the internal multiplexer chain structure.

How is the fine-tune delay controlled?

The FTUNE pin allows continuous delay variation of approximately ±15ps by varying the voltage from VEE to VCC.

Can the device accept TTL control inputs?

Yes, the D inputs can accept CMOS, TTL, or ECL level signals depending on the configuration of the VCF and VEF pins.
