SY89295UMI-TR

Overview

The SY89295UMI-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% power supply and supports frequencies up to 1.5GHz. It features low jitter (<10ps PP total) and accepts CMOS or TTL level control signals. The component is housed in a 32-pin MLF package with an exposed pad for thermal management.

Feature Summary

• Precision LVPECL programmable delay line with guaranteed AC performance over temperature and voltage
• Low-jitter design featuring less than 10ps peak-to-peak total jitter and less than 2ps RMS cycle-to-cycle jitter
• Programmable delay range from 3.2ns to 14.8ns in 10ps increments controlled by a 10-bit word
• Parallel inputs accept LVPECL, CMOS, or LVTTL logic standards

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering

Procurement Notes

Verify the ordering suffix 'MI' corresponds to the MLF-32 package type and Sn-Pb lead finish as specified in the datasheet. Confirm that the 'TR' suffix indicates tape and reel packaging. Ensure the procurement matches the industrial operating temperature range of –40°C to +85°C. Cross-reference the part number with official Microchip documentation to confirm current status and availability.

Selection Notes

Select this component when precise digital delay adjustment is required for high-speed LVPECL signals. It is suitable for applications needing a delay range up to 14.8ns with 10ps resolution. Consider cascading multiple units for extended delay ranges. Ensure the control interface logic levels (CMOS/TTL/LVPECL) match the system requirements via VCF/VEF biasing.

Part Context

The SY89295U belongs to Micrel’s Precision Edge product line, now under Microchip Technology. It is designed for high-speed timing applications requiring low jitter and precise programmability. The device complements other parts like the SY89296U, which offers fine-tune analog control. It is distinct from dual-channel variants like the SY89297U.

Replacement Considerations

The MIC100EP195 is referenced regarding monotonicity improvements. For analog fine-tune control, the SY89296L is an alternative. Dual-channel options include the SY89297U. Verify pinout and electrical specifications before substituting.
