SY89296UTI-TR

Overview

The SY89296UTI-TR is a programmable delay line from the Precision Edge® series, manufactured by Microchip Technology. It operates on a 2.5V ±5% or 3.3V ±10% power supply and supports input frequencies up to 1.5GHz. The device provides a programmable delay range of 3.2ns to 14.8ns in 10ps increments via a 10-bit control word. An additional FTUNE pin allows for continuous fine-tuning within a 40ps range. It features LVPECL inputs and outputs, with a total jitter of less than 10ps peak-to-peak. The component is housed in a 32-pin TQFP package and functions reliably across an industrial temperature range of –40°C to +85°C.

Feature Summary

• Features precision LVPECL programmable delay with low-jitter design capabilities
• Includes analog fine-tune control via voltage input for continuous delay adjustment
• Supports cascading multiple units to extend the overall delay range
• Accepts parallel digital control signals compatible with CMOS, LVTTL, or ECL logic levels

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify the specific ordering suffix 'UTI' corresponds to the TQFP-32 package and tape-and-reel configuration before procurement. Confirm that the lead finish matches project requirements, as this variant may utilize Sn-Pb plating rather than Pb-Free NiPdAu options. Ensure the selected part number aligns with the required operating temperature range and interface standards.

Selection Notes

Select the SY89296UTI-TR when analog fine-tuning capability is required, distinguishing it from the SY89295U which lacks the FTUNE pin. Choose the TQFP package if through-hole compatibility or specific board layout constraints necessitate it over the MLF option. Verify that the 1.5GHz maximum frequency meets the system's clock speed requirements.

Part Context

This component belongs to Micrel’s Precision Edge product line, now managed by Microchip Technology. It serves as the functional counterpart to the SY89295U, adding analog fine-tune control to the standard programmable delay architecture. The device is designed for high-speed timing applications requiring precise signal alignment.

Replacement Considerations

The SY89295U is a related part but lacks the FTUNE pin for analog fine-tuning. No direct substitute part numbers are documented in the provided source material.
