Low Power 12bit 640Msps silicon proven High performance Current Steering DAC IP Core

Overview

12-bit, 640Msps Current Steering DAC is a high-performance current steering DAC supporting data rates up to 640Msps. Each DAC core comprises a current source matrix with quad switching architecture, controlled by an adaptive balanced driver and re-timing latches. It includes all essential calibration circuitry for superior static and dynamic linearity performance. Each channel features an integrated multiplexer for multiplexing 2 lanes of 12-bit data to achieve an effective data rate of 640Msps. A parallel digital interface is provided for external reading and writing of calibration bits.
