The AD9540 includes an RF divider (divide-by-R), a 48-bit DDS core, a 14-bit programmable delay adjustment, a 10-bit DAC (digital-to-analog converter), a phase frequency detector, and a programmable output current charge pump. Incorporat-ing these blocks together, users can generate many useful circuits for clock synthesis. A few simple examples are shown in the Typical Performance Characteristics section.
