The DS1085/DS1085L produces a wide range of frequencies on the main oscillator output (OUT1) and on the reference oscillator output (OUT0). The DS1085/DS1085L allows the user to divide down the frequency (as in the DS1077/DS1077L) but also change the master frequency using DAC and OFFSET. The frequency can be changed by using the internal registers. The DS1085 and DS1085L have the same internal registers, which are discussed in this application note. To assist in determining how to set these registers, without an in-depth understanding of the data sheet, an interactive frequency calculator for the DS1085/DS1085L has been developed. A link to this online interactive calculator is given at the end of the application note. Read full article.
