... GND V OSC Figure 2. Functional Diagram Detailed Description The DS4026 is a TCXO capable of operating at 3.3V ±10%, and it allows digital tuning of the fundamental frequency. The device is calibrated in the factory to achieve an accuracy of ±1ppm over the industrial tem- perature range, and its minimum pullability is ±8ppm with a typical resolution of 1ppb (typ) per LSB. ...

... The monotonic DAC provides an analog voltage based on temperature compensation to drive the variable capacitor. The DS4026 operates as a slave device on the serial bus. Access is obtained by implementing a START condition and providing a device identification code fol- lowed by data. Subsequent registers can be accessed sequentially until a STOP condition is executed ...

... I/O lines SDA and SCL. Within the bus specifications, a standard mode (100kHz maximum clock rate) and a fast mode (400kHz maximum clock rate) are defined. The DS4026 works in both modes. The following bus protocol has been defined (Figure 3): • ...

During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high are interpreted as control signals. Accordingly, the following bus conditions have been defined: ...

... However, in this mode, the direction bit indi- cates that the transfer direction is reversed. Serial data is transmitted on SDA by the DS4026 while the serial clock is input on SCL. START and STOP condi- tions are recognized as the beginning and end of a serial transfer ...
