ASNT5170

Overview

The ASNT5170-PQC is a broadband tunable data and clock phase shifter fabricated in SiGe technology. It provides an adjustable delay range of 260ps controlled via a wide-band differential tuning port with 100MHz bandwidth. The device supports DC to 17Gbps data rates or DC to 14GHz clock frequencies. It features fully differential CML input and output interfaces, with the output providing a 400mV single-ended swing. Power consumption is 610mW using a single +3.3V or -3.3V supply. The component exhibits low jitter (1ps peak-to-peak) and limited temperature variation over the industrial range.

Feature Summary

• Broadband tunable phase shifting capability for both data and clock signals
• Low jitter performance suitable for high-speed measurement applications
• Flexible power supply configuration supporting positive or negative voltage rails
• Integrated on-chip termination resistors for simplified interface design

Applications

• High-speed proof-of-concept prototyping
• High-speed measurement and test equipment
• Variable delay line implementations in signal processing

Procurement Notes

Verify the specific package suffix when ordering, as the datasheet identifies the part as ASNT5170-PQC housed in a standard 24-pin QFN package. Ensure that the center heat slug on the package backside is properly soldered to the appropriate ground or power plane to facilitate heat dissipation during operation. Confirm that the control voltage levels align with the specified differential swing requirements for full adjustment range.

Selection Notes

Select this component when precise variable delay is required for broadband signals up to 17Gbps. The SiGe fabrication ensures high performance and reliability. Consider the thermal management requirements due to the 610mW power consumption. Verify that the system can accommodate the necessary differential control voltages at the icntp/icntn ports to achieve the desired phase shift within the 260ps range.
