12b, 5Gsps, 0.9/1.8V Self Calibrating, Current steering DAC for 5G in UMC 28nm

Overview

DA12CS5GU28HPCP is high performance 12b current steering DAC that supports data rate up-to 5Gsps. DAC core consists of a current source matrix with quad switching architecture, controlled from an adaptive balanced driver and re-timing latches. It has all necessary calibration circuitry to provide excellent static and dynamic linearity performance. There is an integrated multiplexer to multiplex 8 lanes of 12b data to achieve 5Gsps effective data rate. SPI/Parallel digital interface is available for control and configuration of different IP modes.
