ASNT5021

Overview

The ASNT5021-PQC is a high-speed SiGe integrated circuit designed as a broadband data and clock signal distributor. It features one differential input port and three phase-matched differential output ports, 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 780 mW. It utilizes fully differential CML interfaces with internal 50-ohm termination and delivers a 600 mV single-ended swing at the outputs. Key electrical specifications include a maximum additive jitter of 5 ps peak-to-peak, a phase mismatch of 2 ps between outputs, and rise/fall times ranging from 15 to 19 ps.

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 across industrial temperatures

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and pinout configuration. Ensure that the selected variant matches the required thermal management and PCB layout specifications for the intended power supply polarity. Confirm RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a single high-speed signal must be distributed to three destinations with minimal phase skew. Consider the power supply configuration requirements, as positive and negative supply modes necessitate different PCB layouts and termination strategies. Evaluate the thermal dissipation needs given the 780 mW power consumption and the necessity of soldering the center heat slug to the ground plane.

Part Context

The ASNT5021 belongs to ADSANTEC's portfolio of high-speed broadband integrated circuits. Manufactured in Torrance, California, the company specializes in SiGe-based solutions for demanding applications. This specific model addresses the need for precise signal splitting in environments where jitter and phase alignment are critical constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should evaluate alternative distributors based on matching bandwidth, jitter specifications, and package compatibility.
