SY89295UTI-TR

Overview

The SY89295UTI-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 frequencies up to 1.5GHz. The device provides a programmable delay range of 3.2ns to 14.8ns in 10ps increments using a 10-bit control word. It features LVPECL inputs and outputs with low jitter characteristics, including less than 10ps peak-to-peak total jitter. The component is housed in a 32-pin TQFP package and functions within an industrial temperature range of –40°C to +85°C.

Feature Summary

• Precision LVPECL programmable delay line with guaranteed AC performance over temperature and voltage
• Low-jitter design featuring less than 10ps peak-to-peak total jitter and less than 2ps RMS cycle-to-cycle jitter
• Programmable delay range from 3.2ns to 14.8ns in 10ps increments controlled by a 10-bit digital word
• Parallel inputs accept LVPECL or CMOS/LVTTL logic levels for flexible interface compatibility

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify that the ordering suffix UTI corresponds to the T32-1 package type and Sn-Pb lead finish as documented in the official Micrel ordering information. Confirm that the TR suffix indicates tape and reel packaging. Ensure compliance with RoHS directives if lead-free variants are required for specific manufacturing processes.

Selection Notes

Select this component when precise digital delay adjustment is required for high-speed LVPECL signals. Consider cascading multiple units using the D10 bit to extend the delay range beyond the single-device maximum. Verify that the control interface logic levels match the VCF and VEF biasing requirements for the chosen supply voltage.

Part Context

The SY89295U belongs to Micrel’s Precision Edge product line, designed for high-speed timing applications. It serves as a single-channel solution compared to dual-channel alternatives like the SY89297U. The device integrates internal cascade circuitry to allow seamless extension of delay ranges without external gating logic.

Replacement Considerations

The MIC100EP195 is referenced as a predecessor with lower monotonicity. For analog fine-tune control needs, the SY89296L is the designated alternative within the same product family.
