14b, 4Gsps, Self-Calibrating Current Steering IQ DAC for 5G & WIFI6 in samsung 8nm

Overview

DAIQ14CS4G08NLL is high performance 14b current steering IQDAC that supports data rate up-to 4Gsps. Each 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. For each channel, there is an integrated multiplexer to multiplex 8 lanes of 14b data to achieve 4Gsps effective data rate. SPI/Parallel digital interface is available for control and configuration of different IP modes.
