The DS1077L is a dual-output, programmable, fixed-frequency oscillator requiring no externalcomponents for operation. The DS1077L can be used as a processor-controlled frequency synthesizer oras a stand-alone oscillator. The two synchronous output operating frequencies are user-adjustable insubmultiples of the master frequency through the use of two on-chip programmable prescalers anddividers. The specific output frequencies chosen are stored in nonvolatile (EEPROM) memory. TheDS1077L defaults to these values upon power-up.The DS1077L features a 2-wire serial interface that allows in-circuit on-the-fly programming of theprogrammable prescalers (P0 & P1) and divider (N) with the desired values being stored in nonvolatile(EEPROM) memory. Design changes can be accommodated in-circuit, on-the-fly by simply programmingdifferent values into the device (or reprogramming previously programmed devices). Alternatively, forfixed-frequency applications previously programmed devices can be used and no connection to the serialinterface is required. Preprogrammed devices can be ordered in customer-requested frequencies.The DS1077L is available in SO or µSOP packages, allowing the generation of a clock signal easily,economically, and using minimal board area. Chip-scale packaging is also available on request.ApplicationsCable ModemsCell PhonesComputer PeripheralsCopiersPCsPrinters

The DS1086L EconOscillator™ is a 3.3V programmable clock generator that produces a spread-spectrum (dithered) square-wave output of frequencies from 130kHz to 66.6MHz. The selectable dithered output reduces radiated-emission peaks by dithering the frequency 0.5%, 1%, 2%, 4%, or 8% below the programmed frequency. The DS1086L has a power-down mode and an output-enable control for power-sensitive applications. All the device settings are stored in nonvolatile (NV) EEPROM memory allowing it to operate in stand-alone applications.ApplicationsCable ModemsCell PhonesComputer PeripheralsCopiersPCsPrinters

The DS3906 is intended for low resistance, small step-size applications. It contains three nonvolatile (NV), low-temperature coefficient, variable digital resistors that are capable of ohm and subohm increments when used in parallel with a fixed external resistor. All three of the DS3906's resistors have 64 positions (plus a high-Z state) with a pseudo-log response cleverly chosen to have a linear equivalent resistance when paired with an external resistor (see graphs below). The DS3906 also contains 16 bytes of user EEPROM that, in addition to the resistors, are controlled through an I²C-compatible serial interface. Three address pins allow up to eight DS3906s to be placed on the same I²C bus.The DS3906 can also be factory cutomized to provide a variety of transfer functions depending on user requirements.
