ASNT5723-PQC

Overview

The ASNT5723-PQC is a SiGe-based high-speed broadband digital data and clock distributor manufactured by Advanced Science And Novel Technology Company, Inc. It features one differential CML input port and four fully differential amplified output ports with a 660mV single-ended swing. The device supports data rates up to 28 Gbps and frequencies up to 19.5 GHz. It operates on a single +3.3V or -3.3V power supply with typical power consumption of 850mW. Key electrical parameters include a latency of 72 ps, phase mismatch of 2 ps between outputs, and additive jitter of 1.6 ps peak-to-peak for a 10GHz clock. The component is housed in a standard 24-pin QFN package.

Feature Summary

• Provides active splitting of broadband data/clock signals into four phase-matched copies
• Features linearized output buffers to minimize signal undershoot and overshoot
• Supports flexible I/O configurations including AC/DC coupling and single-ended operation
• Fabricated using SiGe technology for high performance and reliability

Applications

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

Procurement Notes

Verify the specific revision number (e.g., Rev. 1.0.2) against the latest manufacturer documentation before procurement. Confirm that the PCB layout matches the required power supply configuration, as positive and negative supply modes necessitate different termination strategies. Ensure the center heat slug is properly soldered to the appropriate plane for thermal management.

Selection Notes

Select this component when a single differential CML source must drive multiple loads with minimal skew. Consider the 72 ps latency and 2 ps phase mismatch for timing-critical applications. Verify that the external circuitry can accommodate the 660mV output swing and that the power supply polarity aligns with the chosen termination scheme.
