ASNT5072

Overview

The ASNT5072-PQC is a narrowband tunable clock phase shifter fabricated in SiGe technology, operating within the 11 GHz to 17 GHz frequency range. It provides an adjustable delay of up to 140 ps with a control bandwidth of 100 MHz via differential tuning ports. The device features fully differential CML input and output interfaces, delivering an 800 mV single-ended swing at the output. Power consumption is specified at 910 mW under a single +3.3 V or -3.3 V supply configuration. The component exhibits low jitter (2 ps peak-to-peak) and maintains phase shift stability within ±12 ps across the 0°C to 125°C temperature range.

Feature Summary

• Provides temperature-stabilized variable delay for high-speed differential signals
• Features linearized data outputs to minimize signal undershoot and overshoot
• Supports flexible power supply configurations using either positive or negative voltage rails
• Integrates internal termination resistors for simplified interface connections

Applications

• High-speed proof-of-concept prototyping
• High-speed measurement and test equipment
• Clock distribution systems requiring precise phase alignment

Procurement Notes

Verify the specific package suffix when ordering, as it denotes the manufacturer, type, and pinout count. Confirm that the design supports the required thermal dissipation through the center heat slug soldered to the appropriate ground or power plane. Ensure the selected power supply polarity matches the intended PCB layout and termination strategy for optimal performance.

Selection Notes

Select this component for applications requiring precise phase adjustment in the Ka-band spectrum. Consider the 140 ps delay range and 100 MHz control bandwidth when designing the tuning circuitry. Evaluate the thermal requirements carefully, as the SiGe fabrication necessitates effective heat dissipation through the package substrate to maintain reliability within the specified junction temperature limits.
