12bits, 1Gsps, Self-Calibrating Current Steering IQDAC

Overview

ZX-DAIQ12CS1G08NLL is high performance 12b current steering IQDAC that supports data rate up-to 1Gsps. 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 2 lanes of 12b data to achieve 1Gsps effective data rate. Parallel digital interface is available to externally read and write calibration bits.

This IP solution is designed and provided by Vervesemi Microelectronics Pvt LTD, a strategic business partner of Zixin.
