ASNT6172-KMN

Overview

The ASNT6172-KMN is a dual-channel asynchronous FIR filter and analog switch fabricated in SiGe technology. It features two fully differential CML-type analog input interfaces and two independent outputs, operating as a non-blocking 2x2 switch with weighted signal mixing capabilities. The device supports data rates from DC to 28 Gbps with a bandwidth of 20 GHz. Each channel contains nine fully controlled taps for pre-emphasis operations. Total gain reaches up to 6 dB. Control is managed via a dual-port 3-wire SPI interface for tap weight and sign adjustments. Power consumption is less than 1.25 W under typical conditions.

Feature Summary

• Dual-channel architecture with nine fully controlled taps per input signal for precise pre-emphasis filtering.
• Operates as an analog non-blocking 2x2 switch allowing independent or mixed weighted output configurations.
• High-speed performance supporting data rates up to 28 Gbps and bandwidth up to 20 GHz.
• Configurable frequency response and gain adjustment through a dedicated 3-wire serial interface.

Applications

• High-speed optical communication systems requiring signal pre-emphasis
• Test and measurement equipment needing adjustable analog filtering
• Data center interconnects utilizing high-bandwidth signal conditioning

Procurement Notes
