Overview
The 12-bit 140 MSPS IQ DAC employs a high-performance current steering architecture and provides optional differential current output or differential voltage output. The bandgap and current source are included to provide a complete DAC. The DAC can be configured to adjust full-scale output range. The DAC uses segmentation architecture combined with Q2 random walk algorithm to achieve excellent dynamic and static performance, wide output bandwidth. An internal resistive load together with current source is used to set differential voltage output, which independent from process, supply and temperature. LVDS transmitter, output buffers and IO PADs are included.
The block is designed on TSMC CMOS 65 nm technology.

DAC 2022 - Is it too risky not to adopt RISC-V?

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.
