DS1085  
External control inputs, CTRL1 and CTRL0, enable or disable the two oscillator outputs. Both outputs  
feature a synchronous enable that ensures no output glitches when the output is enabled and a constant  
time interval (for a given frequency setting) from an enable signal to the first output transition. These  
inputs also can be configured to disable the master oscillator, putting the device into a low-power mode  
for power-sensitive applications.

OVERVIEW  
A block diagram of the DS1085 is shown in Figure 1. The DS1085 consists of five major components:  
CꢀMaster oscillator control DAC  
CꢀInternal master oscillator (66MHz to 133MHz)  
CꢀPrescalers (divide-by-1, 2, 4, or 8)  
CꢀProgrammable divider (divide-by-1 to 1025)  
CꢀControl registers  
The internal master oscillator provides the reference clock (MCLK), which is fed to the prescalers and  
programmable dividers. The frequency of the oscillator can be user-programmed over a two-to-one range  
in increments equal to the step size, by means of a 10-bit control DAC. The master oscillator range is  
66MHz to 133MHz, which is larger than the range possible with the 10-bit DAC resolution and available  
step sizes. Therefore, an additional register (OFFSET) is provided that can be used to select the range of  
frequency over which the DAC is used (see Table 1).
