ASNT5024-KMC

Overview

The ASNT5024-KMC is a high-speed broadband signal distributor fabricated in SiGe technology. It provides one differential CML input and three phase-matched differential CML outputs, functioning as an active data/clock amplifier and splitter. The device supports data rates up to 28 Gbps and frequencies up to 17 GHz. It operates on a single +3.3V or -3.3V power supply with a typical power consumption of 780 mW. Key electrical parameters include a latency of 64 ps, a phase mismatch of 2 ps between outputs, and additive jitter of 5 ps peak-to-peak. The package is a custom 24-pin CQFP.

Feature Summary

• Provides active splitting of broadband data and clock signals into three phase-matched copies
• Features fully differential CML interfaces with internal 50 Ohm termination to Vcc
• Operates with either positive (+3.3V) or negative (-3.3V) single power supply configurations
• Utilizes SiGe fabrication for high performance and reliability over industrial temperature ranges

Applications

• High-speed measurement and test equipment
• Signal distribution in multi-channel data acquisition systems
• Clock distribution networks requiring low jitter and matched delays

Procurement Notes

Verify the specific revision number (e.g., Rev 4.3.2) against the manufacturer's current documentation to ensure compatibility with design requirements. Confirm that the ordering suffix matches the required package type and pinout configuration. Ensure that the procurement source provides valid RoHS compliance documentation per 2011/65/EU standards.

Selection Notes

Select this component when a single high-speed differential signal requires amplification and distribution to three separate paths with minimal phase skew. Consider the thermal management requirements due to the 780 mW power dissipation and the need for a heat slug connection. Evaluate whether the AC or DC coupling mode aligns with the interface voltage levels of the connected devices.

Part Context

This part belongs to ADSANTEC's family of high-speed SiGe integrated circuits designed for signal conditioning and distribution. Unlike multiplexers or serializers, the ASNT5024-KMC focuses on fan-out applications, ensuring signal integrity across multiple channels without serialization overhead.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult ADSANTEC directly for potential cross-references or updated revisions within the same product line.
