ASNT1123-PQP

Signal Switches, Multiplexers, Decoders Overview

The ASNT1123-PQP is a SiGe-based DC to 32 Gbps broadband digital 4:1 multiplexer. It accepts four parallel differential CML data inputs at quarter-rate (up to 8 Gbps) and serializes them into a high-speed full-rate output stream (up to 32 Gbps). The device supports half-rate clock input in DDR mode and provides a divided-by-4 clock output. It operates on a single +3.3V or -3.3V supply with 1.15W power consumption, featuring low jitter and phase-matched outputs within a 36-pin QFN package.
