SY89296UMG-TR

Overview

The SY89296UMG-TR is a programmable delay line from the Precision Edge® series manufactured by Microchip Technology. It provides a delay range of 3.2ns to 14.8ns in 10ps increments, with an additional analog fine-tune control via the FTUNE pin offering approximately 40ps/V adjustment. The device operates on a 2.5V ±5% or 3.3V ±10% supply and supports LVPECL inputs/outputs. It features low jitter (<10ps PP total, <2ps RMS cycle-to-cycle) and accepts CMOS/TTL control signals. The component is housed in a 32-pin MLF package and operates within -40°C to +85°C.

Feature Summary

• Analog fine-tune capability via FTUNE pin for continuous delay adjustment
• Low-jitter design ensuring high signal integrity
• Flexible digital control interface accepting CMOS or TTL levels
• Internal circuitry supporting cascading for extended delay ranges

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead finish and packaging type. The 'MG' suffix indicates a Pb-Free NiPdAu finish, while other variants may use Sn-Pb. Confirm that the TR suffix corresponds to the tape and reel configuration required for your assembly process. Cross-reference the part number with the latest datasheet revision to ensure compatibility with current RoHS standards.

Selection Notes

Select the SY89296UMG-TR when analog fine-tuning is required, as opposed to the SY89295U which lacks the FTUNE pin. Ensure the system voltage aligns with the 2.5V or 3.3V operating requirements. Verify that the 32-pin MLF package fits the PCB footprint constraints. Consider cascading multiple units if the maximum single-device delay of 14.8ns is insufficient for the application timing needs.

Part Context

This component belongs to Micrel’s (now Microchip) Precision Edge® product line, designed for high-speed applications. It serves as an enhanced version of the SY89295U by adding analog fine-tune control. The device is intended for precision timing applications requiring both digital programmability and analog adjustability within a compact surface-mount package.

Replacement Considerations

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