SY89295UTG-TR

Overview

The SY89295UTG-TR is a programmable delay line from the Precision Edge series, manufactured by Microchip Technology. It delays LVPECL input signals using digital control bits, offering a delay range of 3.2ns to 14.8ns in 10ps increments. The device operates on a 2.5V ±5% or 3.3V ±10% supply and supports frequencies up to 1.5GHz. It features low jitter (<10ps PP total, <2ps RMS cycle-to-cycle) and accepts CMOS/TTL control levels. The component is housed in a 32-pin TQFP package with an industrial temperature rating of –40°C to +85°C.

Feature Summary

• Precision LVPECL programmable delay line with guaranteed AC performance over temperature and voltage
• Low-jitter design ensuring high signal integrity for high-speed applications
• Parallel inputs accept LVPECL or CMOS/LVTTL logic standards

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify the specific ordering suffix 'UTG' against official manufacturer documentation to confirm lead finish and package type. Confirm that the TR suffix indicates tape and reel packaging. Ensure compatibility with required operating temperatures and voltage specifications before procurement.

Selection Notes

Select this component when precise digital delay adjustment is required for LVPECL signals. Consider cascading multiple units via the D10 bit to extend the delay range beyond the single-device maximum. Verify interface requirements for control bits to ensure compatibility with available logic levels.

Part Context

The SY89295U belongs to Micrel’s (now Microchip) Precision Edge product line, designed for high-speed timing applications. It serves as a programmable alternative to fixed delay lines, allowing dynamic adjustment of signal propagation time through digital control words.

Replacement Considerations

The MIC100EP195 is referenced as a predecessor with lower monotonicity. No direct public substitute part numbers are confirmed in the provided documentation.
