SY89296UMI-TR

Overview

The SY89296UMI-TR is a programmable delay line from the Precision Edge series, manufactured by Microchip Technology. It delays LVPECL input signals using digital control words and an analog fine-tune voltage. The device provides a programmable delay range of 3.2ns to 14.8ns in 10ps increments, with an additional continuous adjustment capability of approximately 40ps via the FTUNE pin. It operates on a 2.5V ±5% or 3.3V ±10% supply and supports maximum frequencies exceeding 1.5GHz. Key electrical characteristics include less than 10ps peak-to-peak total jitter and less than 2ps RMS cycle-to-cycle jitter. The component is housed in a 32-pin MLF package.

Feature Summary

• Features a dedicated FTUNE pin for continuous analog delay fine-tuning over a 40ps/V range.
• Supports cascading multiple units via internal circuitry to extend the total delay range.
• Accepts parallel control inputs compatible with CMOS, LVTTL, or LVPECL logic levels.

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify that the specific ordering suffix matches the required lead finish and packaging format. The 'MI' designation indicates the MLF-32 package type, while the 'TR' suffix confirms tape and reel delivery. Confirm RoHS compliance status and ensure the selected variant aligns with the intended operating temperature range requirements.

Selection Notes

Select this model when analog fine-tuning capabilities are necessary, as it differs from the SY89295U which lacks the FTUNE pin. Ensure the design accommodates the 32-pin MLF package dimensions and thermal dissipation requirements. Verify that the system power supply voltages fall within the specified 2.5V or 3.3V operational limits.

Part Context

This component belongs to Micrel's Precision Edge product line, now managed by Microchip Technology. It serves as a high-speed timing element designed for applications requiring precise signal alignment. The device is characterized for industrial temperature ranges and offers low-jitter performance suitable for demanding clock distribution networks.

Replacement Considerations

The SY89295U is a related part within the same family but does not include the FTUNE fine-tuning feature. Designers requiring analog delay adjustment must use the SY89296U; the SY89295U is suitable only if discrete digital steps are sufficient.
