SY89296UTG-TR

Overview

The SY89296UTG-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 offers fine-tune analog adjustment via the FTUNE pin. The device provides a total delay range of 3.2ns to 14.8ns in 10ps increments, with an additional 40ps continuous variation capability. It operates on a 2.5V ±5% or 3.3V ±10% supply voltage and supports frequencies up to 1.5GHz. The component features low jitter performance (<10psPP total) and is housed in a 32-pin TQFP package.

Feature Summary

• Supports parallel inputs accepting LVPECL, CMOS, or LVTTL logic levels for flexible interfacing.
• Includes internal cascade circuitry allowing multiple devices to be connected without external gating.
• Provides VBB output reference voltage for single-ended input biasing and AC-coupled re-biasing.

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify the specific ordering suffix 'UTG' against the manufacturer's official documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with industrial temperature ranges (-40°C to +85°C) and required supply voltages (2.5V or 3.3V). Cross-reference part numbers with current distributor listings to confirm availability and authenticity before procurement.

Selection Notes

Select the SY89296UTG-TR when analog fine-tuning of delay is required, distinguishing it from the SY89295U which lacks the FTUNE pin. Consider the 32-pin TQFP package if through-hole or standard surface-mount assembly is preferred over the MLF variant. Verify that the 10-bit digital control interface and ECL-level control inputs align with the system's logic standards.

Part Context

This component belongs to Micrel’s high-speed Precision Edge® product line, now under Microchip Technology. It serves as an enhanced version of the SY89295U by adding analog fine-tune control capabilities. The device is designed for precision timing applications requiring high-frequency operation and low jitter characteristics within industrial temperature environments.

Replacement Considerations

The SY89295U is a related part but lacks the FTUNE fine-tune control feature. No direct public substitute part numbers are confirmed in the provided documentation.
