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.

Specifying a PLL Part 1: Calculating PLL Clock Spur Requirements from ADC or DAC SFDR

In high end RF systems, such as 5G radios, the requirements are so stringent that the source of this strongest unwanted tone can be the PLL. This article outlines how spurs in the input clock to the ADC or DAC may limit the SFDR. This in turn will set the requirements for the spurs for the input clock (from a PLL), in order to achieve a specific SFDR.
