VDAC
Overview
This IP is composed of a single to sextuple channel 10-bit, 300MHz DAC designed for 40nm CMOS technology supplied at 3.3V. Each independent DAC uses a segmented current steering architecture, combined with an improved two-dimensional centroid switching scheme, to achieve simultaneously high update rates, at least 10-bit of intrinsic static accuracy, and very good dynamic characteristics. The circuit is a current output DAC designed to be loaded by double terminated 75 Ohm Lines. The DAC full-scale current is set with the internal bandgap reference voltage, an external resistor and a digital 6 bit word. Sense comparators are included to allow power savings when video cables are disconnected. This Video DAC is suitable for RGB video and HDTV or standard Video (Component, S-Video, Composite) applications.
