ASNT5073A

Overview

The ASNT5073A is a wideband clock phase shifter with amplitude control fabricated in SiGe technology. It operates from 0.5 MHz to 17 GHz and provides a delay adjustment range of 150 ps at 15 GHz, or 160 ps at 10 GHz. The device features fully differential CML input and output interfaces with internal 50 Ohm termination. Output amplitude is adjustable from 0.2 V to 0.9 V via a dedicated tuning port. It requires a single +3.3 V or -3.3 V power supply and consumes 1.3 W. The part is housed in a standard 24-pin QFN package.

Feature Summary

• Wideband tunable clock phase shifting capability across the 0.5 MHz to 17 GHz frequency range
• Low jitter performance suitable for high-speed measurement and test equipment applications
• Independent wide-bandwidth differential tuning ports for precise delay and amplitude control

Applications

• High-speed measurement and test equipment
• Clock distribution networks requiring variable delay
• Signal processing systems needing amplitude adjustment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to ensure correct package type and pinout configuration. Confirm that the procurement channel sources components directly from Advanced Science And Novel Technology Company, Inc. or authorized distributors to guarantee authenticity. Check RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a wide bandwidth up to 17 GHz is required alongside independent amplitude control. Ensure the system design supports the specified 1.3 W power consumption and thermal requirements for the 24-pin QFN package. Verify compatibility with CML logic levels and the chosen power supply polarity (+3.3 V or -3.3 V) before integration.

Part Context

The ASNT5073A belongs to the ASNT5073 series of clock signal conditioning devices produced by Advanced Science And Novel Technology Company, Inc. It utilizes Silicon Germanide (SiGe) fabrication technology to achieve high performance and reliability. The device is designed to provide stable delay characteristics over industrial temperature ranges.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative SiGe-based phase shifters only if they match the 17 GHz bandwidth and CML interface specifications.

FAQ

What is the recommended DC signaling mode for optimal performance?

Differential DC signaling mode is recommended for optimal performance. In this mode, the input signal's common mode voltage must comply with the electrical specifications.

How is the output amplitude controlled?

The output amplitude is controlled through the wide-band differential tuning port labeled tnp/tnn, allowing adjustment from 0.2 V to 0.9 V.

What are the absolute maximum ratings for the supply voltage?

The absolute maximum rating for the supply voltage (vee) is -3.6 V. Exceeding these limits may cause damage or reduce reliability.
