ASNT5023

Overview

The ASNT5023-PQC is a high-speed broadband signal distributor fabricated in SiGe technology. It features one differential CML input and four differential amplified outputs, supporting data rates up to 28 Gbps and frequencies up to 17 GHz. The device provides matched phase delays with a typical latency of 100 ps and phase mismatch of 2 ps between outputs. It operates on a single +3.3V or -3.3V supply, consuming approximately 1.22W. Outputs deliver a 600mV single-ended swing with internal 50Ohm termination to Vcc.

Feature Summary

• Provides active splitting of broadband data/clock signals into four phase-matched copies
• Features linearized output buffers to minimize undershoot and overshoot
• Supports flexible I/O configurations including differential, AC/DC coupled, and single-ended modes
• Operates with either positive or negative power supply configurations

Applications

• High-speed measurement and test equipment
• Broadband data distribution networks
• Clock signal distribution systems

Procurement Notes

Verify the specific ordering suffix PQC to confirm the 24-pin QFN package configuration. Ensure the procurement documentation matches the manufacturer's part identification standards. Confirm RoHS compliance status as defined in the package information section of the official datasheet for regulatory requirements.

Selection Notes

Select this component when a single differential CML signal requires distribution to four distinct paths with minimal phase skew. Consider the 100 ps latency and 2 ps phase mismatch specifications for timing-critical applications. Evaluate the power supply polarity requirement (+3.3V vs -3.3V) as it dictates the necessary PCB layout and AC/DC coupling termination strategies for the I/O interfaces.

Part Context

The ASNT5023 belongs to ADSANTEC’s family of high-speed SiGe integrated circuits designed for signal integrity and distribution. Unlike multiplexers that combine signals, this device focuses on fan-out capabilities. The PQC suffix specifically denotes the standard 24-pin QFN package variant, distinguishing it from other potential packaging options within the broader ASNT series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate functional compatibility regarding CML interface, voltage levels, and bandwidth if considering alternative vendors.
