SY89296UTI

Overview

The SY89296UTI 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 40ps fine-tune control via the FTUNE pin. The device operates on a 2.5V ±5% or 3.3V ±10% supply and supports frequencies up to 1.5GHz. It features LVPECL inputs and outputs, low jitter (<10psPP total), and accepts CMOS/TTL control signals. 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

• Programmable delay adjustment using a 10-bit digital control word with 10ps step resolution
• Analog fine-tuning capability through the FTUNE pin for continuous delay variation
• Low jitter design ensuring high signal integrity at frequencies exceeding 1.5GHz
• Internal cascade circuitry allowing multiple units to be connected for extended delay ranges

Applications

• Clock de-skewing in high-speed data transmission systems
• Timing adjustments for precise synchronization
• Aperture centering in sampling applications

Procurement Notes

Verify the specific ordering suffix UTI corresponds to the 32-pin TQFP package type when sourcing components. Confirm lead finish specifications, as standard versions utilize Sn-Pb while Pb-Free variants carry different suffixes. Ensure compatibility with the required operating voltage and temperature range before finalizing procurement orders.

Selection Notes

Select the SY89296UTI over the SY89295U when analog fine-tune control via the FTUNE pin is required. Verify that the 32-pin TQFP package meets board layout constraints compared to the MLF option. Ensure the application requires LVPECL input/output signaling and can accommodate the necessary power supply decoupling for stable operation.

Part Context

The SY89296U belongs to Micrel’s Precision Edge product line, designed for high-speed timing applications. It serves as an enhanced version of the SY89295U by adding analog fine-tune control capabilities. The device is part of a family of precision delay lines intended for demanding clock distribution and synchronization tasks in telecommunications and computing infrastructure.

Replacement Considerations

The SY89295U is a related component but lacks the FTUNE pin for analog fine-tuning. When replacing the SY89296UTI, verify if the analog control feature is essential for the specific application requirements.
