ASNT5075

Overview

The ASNT5075-PQC is a broadband tunable phase shifter fabricated in SiGe technology, designed for high-speed data and clock signal processing. It supports data rates up to 28 Gbps and clock frequencies up to 14 GHz. The device provides a delay adjustment range of 260 ps with an output jitter of 3 ps peak-to-peak. It operates on a single +3.3V or -3.3V power supply, consuming approximately 1.6W. The IC features fully differential CML input and output interfaces with internal 50 Ohm termination. Control is managed via a wide-band differential tuning port (icntp/icntn) offering 1 GHz bandwidth. The component is housed in a standard 24-pin QFN package.
