ASNT1122-KHC

Signal Switches, Multiplexers, Decoders Overview

The ASNT1122-KHC is a high-speed broadband selector switch fabricated in SiGe technology, designed to route one of four single-ended CML inputs to a differential CML output. It supports data rates up to 32 Gbps and operates within a frequency range of 0 Hz to 16 GHz. The device features low jitter (2 ps peak-to-peak additive) and adjustable duty cycle via an external analog voltage. Power consumption is 300 mW with a single +3.3V or -3.3V supply. It utilizes a custom 24-pin CQFN package with a center heat slug for thermal management.
