ASNT5107-KHC

Overview

The ASNT5107-KHC is a broadband tunable signal phase shifter fabricated in SiGe technology, designed for data and clock signals up to 32 Gbps. It features a fully differential CML interface with internal 50 Ohm termination and operates on a single +3.3V or -3.3V supply. The device provides an adjustable delay range of 0 to 110 ps controlled via the icntp/icntn port. It incorporates automatic temperature and process corner delay compensation, duty cycle distortion correction, and manual peaking control through efcrl. Power consumption is adjustable between 630 mW and 1150 mW using the icrl port.

Feature Summary

• Advanced control system with automatic temperature and process corner delay compensation
• Duty cycle distortion compensation with adjustable gain and feedback loops
• Manual internal peaking control to optimize frequency response and eye diagrams
• Adjustable power consumption allowing trade-off between operational speed and energy use

Applications

• High-speed measurement and test equipment requiring extremely low jitter
• Variable delay lines for high-speed data and clock signal processing
• Broadband phase shifting in telecommunications infrastructure

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and pinout configuration. Ensure that the procurement channel provides valid RoHS compliance certificates per 2011/65/EU standards. Confirm that the component matches the custom 24-pin CQFN package specifications before finalizing orders.

Selection Notes

Select this component when precise phase adjustment is required for signals up to 32 Gbps. Consider the adjustable power consumption feature if thermal management or efficiency is critical. Verify compatibility with CML logic levels and ensure the control voltage ranges for tuning ports align with the system's available reference voltages.

Part Context

The ASNT5107-KHC belongs to the ADSANTEC family of high-speed signal processing components. Manufactured using Silicon-Germanium (SiGe) technology, it targets applications demanding high performance and reliability. The part integrates advanced control mechanisms to maintain signal integrity across varying environmental conditions.

Replacement Considerations

No public confirmed substitute part numbers are documented for this specific model. Designers should evaluate alternative phase shifters based on matching SiGe fabrication, CML interface requirements, and comparable bandwidth capabilities.

FAQ

How is the power consumption adjusted?

Power consumption is adjusted via the single-ended analog control port icrl. Higher voltages at this input correspond to higher power consumption, which increases the operational speed of the part.

What is the function of the efcrl port?

The efcrl port allows manual adjustment of internal peaking by varying currents of internal emitter followers. This helps adjust the frequency response and improve output eye diagrams under various operating conditions.

Can the device operate with AC coupling?

Yes, the I/Os support AC coupling. In this mode, the input termination automatically provides the required common mode voltage, unlike DC coupling where the input signal's common mode must comply with specifications.
