ASNT5121B-KHC

Overview

The ASNT5121B-KHC is a high-speed SiGe clock amplifier and distributor designed for broadband signal splitting in measurement equipment. It features one differential CML input and three matched-phase differential outputs, operating from DC to 35 GHz. The device supports single +3.3V or -3.3V power supplies with a typical consumption of 760 mW. Electrical specifications include a peak-to-peak output jitter of 200 fs, rise/fall times of 6 ps (typical), and a 400 mV single-ended output swing. It utilizes a custom 24-pin CQFN package with an integrated thermal slug.

Feature Summary

• Provides active broadband clock signal splitting with phase-matched outputs
• Features low jitter performance and limited temperature variation over the industrial range
• Supports flexible interface configurations including AC/DC coupling and single-ended operation

Applications

• High-speed measurement and test equipment
• Broadband clock distribution systems
• Signal processing applications requiring precise phase matching

Procurement Notes

Verify the specific revision level against the manufacturer's documentation prior to ordering. Confirm that the required power supply configuration matches the PCB layout design, as positive and negative supply modes require different termination strategies. Ensure compliance with RoHS directives if applicable to the target market.

Selection Notes

Select this component when a single high-frequency clock source must be distributed to three separate paths with minimal phase skew. Consider the thermal requirements of the CQFN package and ensure adequate heat dissipation through the center slug. Verify that the system logic levels are compatible with the specified CML interface and voltage swings.
