SY89297UMH

Overview

The SY89297UMH is a dual-channel programmable delay line supporting DC to 3.2 Gbps data rates and 1.6 GHz clock frequencies. It provides a 5 ns programmable delay range with 5 ps resolution, ensuring monotonicity within ±25 ps and integral non-linearity of ±15 ps. The device operates on a 2.5V or 3.3V supply, drawing up to 250 mA. It features a 3-pin serial interface for independent channel control and supports cascading. Packaged in a 24-lead QFN, it functions within an ambient temperature range of -40°C to +75°C.

Feature Summary

• Dual-channel architecture with independent 10-bit serial programming
• High-resolution 5 ps step increments across a 5 ns delay range
• Guaranteed AC performance over specified voltage and temperature variations
• Low-jitter design with typical 1 ps RMS random jitter

Applications

• Clock de-skewing
• Timing adjustments
• Aperture centering
• System calibration

Procurement Notes

Verify the specific suffix 'H' indicates the extended industrial temperature range of -40°C to +75°C, which differs from the standard 'G' variant. Confirm package availability as tube or reel configurations may vary by distributor. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference datasheet revision DS20005835A for accurate electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when precise, programmable delay adjustment is required for high-speed CML signals. The dual-channel capability allows synchronized timing control for multiple data paths. Verify that the operating environment remains within the -40°C to +75°C limit. Consider the 24-lead QFN footprint for PCB layout constraints. Evaluate power consumption against system thermal budgets given the maximum current draw.

Part Context

This part belongs to the Precision Edge family of delay lines manufactured by Microchip Technology. It serves as a dual-channel counterpart to single-channel variants like the SY89295U. The device utilizes advanced CML technology to maintain signal integrity at high frequencies. It is designed for applications requiring deterministic timing adjustments in complex digital systems.

Replacement Considerations

The SY89297UMG is a direct functional replacement offering an extended temperature range of -40°C to +85°C. Both parts share identical pinouts, electrical characteristics, and packaging dimensions. Designers must verify that the target application's thermal environment falls within the -40°C to +75°C limit of the UMH variant before substitution.
