The Maxim Integrated DS1077U-100+ programmable oscillator is designed for applications that require precision timing, such as clock/timing, communications and embedded systems. This device has a very high performance in terms of its accuracy, stability, and capability of being programmed. It is the ideal choice for applications where size and power are critical, such as mobile applications and other battery operated devices.

The DS1077U-100+ programmable oscillator employs a high frequency oscillator circuit composed of voltage controlled crystal oscillator (VCXO) and a phase locked loop (PLL) with an adjustable frequency divider. A programmable hardware-based voltage-controlled crystal oscillator (PVXCO) controls the frequency range and fidelity of the frequency control resolution of the device. This PLL also controls the output frequency stability and accuracy, as well as permitting the user to program frequencies for applications requiring specific timing.

The built-in voltage regulator makes this device an ideal choice for many applications where interference-prone areas exist, such as communications and other mobile applications. Additionally, its low power consumption, freedom from EMI, low jitter performance, and able to run several selectable voltage ranges makes DS1077U-100+ programmable oscillator the ideal choice for system integrators.

The DS1077U-100+ programmable oscillator offers several user programmable features with a power on reset. It has an adjustable output frequency range of 3.2 to 125MHz, with frequency resolution down to 0.1Hz and phase noise as low as -110dBc at 1KHz offset. Furthermore, the device also provides numerous other features, including programmable spread spectrum, start/stop function, frequency-hopping, output modulation, current-controlled blanking, selectable slew rate and output drive levels.

With the integrated on-chip intelligent programming capability, the DS1077U-100+ programmable oscillator can be configured and programmed with a number of different programming options. Through the on-chip memory, various settings can be programmed and logged, and user can modify the settings of this device. Additionally, the device can be programmed and monitored through a custom serial interface.

In summary, the Maxim Integrated DS1077U-100+ programmable oscillator is a highly integrated, high performance, and low power consumption device, ideal for applications where size and accuracy are critical. Its wide operating temperature range, low power consumption, low jitter performance, and on-chip programming capabilities makes it one of the best choices for clock and timing applications. The device has the capability to generate several selectable frequencies and offers flexible and portable frequency tuning, making it ideal for system integrators, communications, and other embedded systems.
