ASNT1140-KMA

Signal Switches, Multiplexers, Decoders Overview

The ASNT1140-KMA is a programmable DDR digital multiplexer and serializer manufactured by ADSANTEC. It converts 16 parallel data channels into a high-speed serial bit stream, supporting data rates from DC to 50 Gbps in dual data rate clocking mode. The device operates on a single +3.3V power supply with a maximum power consumption of 1520 mW at peak speed. It features an industrial temperature range from -25°C to 125°C junction temperature and utilizes a custom 100-pin CQFP package measuring 13mm x 13mm.
