ASNT5024

Overview

The ASNT5024-PQC is a high-speed SiGe integrated circuit functioning as a broadband data and clock signal distributor. It accepts one differential input and provides three phase-matched differential outputs, supporting data rates up to 28 Gbps and frequencies up to 17 GHz. The device features fully differential CML interfaces with internal 50-ohm termination and delivers a 600 mV single-ended output swing. Power consumption is specified at 780 mW under a single +3.3 V or -3.3 V supply configuration. 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 component is housed in a standard 24-pin QFN package.

Feature Summary

• Provides active splitting of broadband data and clock signals into three phase-matched copies
• Supports flexible interface configurations including AC/DC coupling and single-ended operation
• Fabricated using SiGe technology for high performance and reliability over industrial temperature ranges

Applications

• High-speed measurement and test equipment
• Signal distribution in broadband communication systems
• Clock distribution networks requiring low jitter and matched delays

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the datasheet identifies the ASNT5024-PQC variant as the 24-pin QFN configuration. Confirm power supply requirements align with the recommended operating conditions of ±3.3 V. Ensure PCB layout accounts for the center heat slug connection to the appropriate ground or power plane depending on the chosen supply polarity. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a single high-speed differential signal requires distribution to three separate paths with minimal phase deviation. The 28 Gbps bandwidth suits applications involving modern serial data standards. Consider the 64 ps latency and 2 ps phase mismatch specifications for timing-critical designs. Evaluate the thermal management requirements due to the 780 mW power dissipation within the compact 24-pin QFN footprint.
