SY89297UMG

Overview

The SY89297UMG is a dual-channel programmable delay line supporting data rates up to 3.2 Gbps. It provides a programmable delay range of 5 ns with 5 ps resolution increments. The device features a serial programming interface (SDATA, SCLK, SLOAD) and guarantees AC performance over temperature and voltage. It operates on a supply voltage of 2.5V ±5% or 3.3V ±10%. The unit is housed in a 24-lead 4 mm x 4 mm QFN package.

Feature Summary

• Dual-channel architecture with independent CML outputs
• Serial control interface for precise delay adjustment
• Low-jitter design ensuring signal integrity
• Capability to cascade multiple units for extended delay

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's product identification system. The 'MG' suffix indicates a 24-lead QFN package with an industrial temperature range of -40°C to +85°C. Confirm that the required packaging format matches the intended manufacturing process, as tube and reel options exist within the same family.

Selection Notes

Select this component when dual-channel precision delay is required for high-speed digital signals. Ensure the input signal swing and termination match the specified CML requirements. Verify that the available 5 ns delay range meets the application needs, as single-channel alternatives like the SY89295U may be considered if only one channel is necessary.

Part Context

This part belongs to the Precision Edge series of timing components manufactured by Microchip Technology. It serves as a dual-channel solution compared to single-channel variants such as the SY89295U and SY89296U. The device is designed for applications requiring precise synchronization in automated test equipment and broadcasting systems.

Replacement Considerations

The SY89295U and SY89296U are documented single-channel delay lines from the same family. These parts offer similar functionality but provide only one channel instead of two. Evaluate these alternatives if the application requires fewer channels or different pin configurations.
