ASNT5023-KMM

Overview

The ASNT5023-KMM is a high-speed broadband signal distributor fabricated in SiGe technology. It features one differential CML input and four phase-matched differential CML outputs, supporting data rates up to 28 Gbps and frequencies up to 17 GHz. The device operates on a single +3.3V or -3.3V power supply with a typical power consumption of 1.22W. Key electrical specifications include a latency of 100 ps, a phase mismatch of 2 ps between outputs, and an additive jitter of 5 ps peak-to-peak. Outputs provide a 600 mV single-ended swing with internal 50 Ohm termination.

Feature Summary

• Provides active splitting of broadband data and clock signals into four phase-matched copies
• Features linearized output buffers to minimize undershoot and overshoot
• Supports flexible I/O configurations including AC/DC coupling and single-ended operation
• Utilizes a custom 44-pin CQFP package with a center heat slug for thermal management

Applications

• High-speed measurement and test equipment
• Signal distribution networks requiring phase-matched outputs
• Broadband data and clock amplification systems

Procurement Notes

Verify the specific ordering suffix KMM corresponds to the 44-pin CQFP package configuration. Confirm that the required power supply polarity matches the PCB layout design, as positive and negative supply configurations necessitate different termination strategies. Ensure compliance with RoHS standards if applicable to the target assembly environment.

Selection Notes

Select this component when a single high-speed signal must be distributed to four distinct paths with minimal phase deviation. Consider the 100 ps latency and 2 ps phase mismatch for timing-critical applications. Evaluate the 1.22W power dissipation against available thermal solutions, utilizing the package's center heat slug for effective heat transfer to the ground plane.

Part Context

This device belongs to ADSANTEC's family of high-speed SiGe integrated circuits designed for signal integrity. Unlike multiplexers found in other series, this part functions specifically as a splitter/distributor. It complements other ADSANTEC components by providing the necessary fan-out capability for high-frequency clock and data lines without significant signal degradation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate alternative SiGe distributors from other manufacturers only if they can match the 28 Gbps rate, 44-pin CQFP footprint, and specific phase matching requirements.
